VFS: Cannot open root device "302" or unknown-block (3,2)
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on unknown-block (3,2)

it seems like a unsupported filesystem error. have u checked the filesystem of root partion is supported in kernel (not module)? u must touch filesystems remove unnecessary filesystem supports.

And also you might want those IDE support compiled IN the kernel.

[edit]
Check also if you are trying to use a RAM disk (which you dont need, unless you gonna boot that kernel from a CD/Floppy)

i get this alot with redhat / fedora distro's

get into /boot/grub folder and open manu.lst

you will probable find that you have a kernel parameter like so
' kernel /boot/vmlinuz-2.6.5 ro root=/LABEL=/'

works with some kernels, not with others... change it to
' kernel /boot/vmlinuz-2.6.5 ro root=/dev/hdb1'

change hdb1 to whereever your root partiton is.

just say that after i posted....
but lilo is just as capable of passing kernel options as grub is it not ?

im sure you can adjust the syntax accordingly.
