How do I how do you increase color depth from 24 to 32 bit (redhat 8.0)

hello this is my second post ever.
I've been using linux on and off for over sixmonths.
i started with suse 8.1, it was cool, Nvidia drivers were easy to install and use. i didnt like the way it handelled the drive partitioning nor do i want deal with windows emulation . Its kde seems more stable than redhat 8.0's but its gnome sukks and and cant be compared to rh8.0's, all the cool apps like pan
-which by the way is an excellent newsgroup agent- are on gnome. word out
is that mandrake 9.1(or whatever x.x) is much better. To make a long story short redhat 8.0 is doing right by me so far (being that i nolonger want to pay insane amounts of cash for windows apps). ok, now to the meat of my question. can I increase color depth from 24 to 32 bit? and if so can anyone show me how to do this.
I've adjustted my inittab to run level 1, installed the, edited xf86config to not load "dri (i didnt have a "glcore" so i didnt need to do anything about that), replaced nv with nvidia, readjustted my inittab to run level 5, back to xserver successfully.
I also downloaded and ran a file by the name of NVIDIA_GLX-1.0-4191.src.rpm on gnome which used "install packages"
to update my system. I do not now if installing this package was the write thing to do and i have seen no changes to my system post that action.
i went to xdisplay and noticed that the maximum color depth is still 24bit video card sumary indicates that the current vidcard is NVIDIA GeForce 2MX (generic), memory size is 64megs driver is nvidia. and 3d acceleration is a blank incacesible box .
the area for special options is blank.

XFree86 Version 4.2.1 (Red Hat Linux release: 4.2.1-21)
Linux version 2.4.18-14
and this is what my XF86Config file looks like:
# File generated by anaconda.

Section "ServerLayout"
Identifier "Anaconda Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Mouse1" "SendCoreEvents"
InputDevice "Keyboard0" "CoreKeyboard"

Section "Files"
# The location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
# If you'd like to switch the positions of your capslock and

Are you sure you know what you want here ? The difference between 24bit and 32bit is an 8bit alpha channel which is used for opacity/transparency. AFAIK this is not supported at all for any window manager. 24bit is "truecolour" as it is, you are pretty much at the top already.
