There's no real driver to be had. Its a matter of finding out what the HorizSync and VertRefresh ranges of the monitor are and inputting those by hand. It'll be on the sony site for the monitor, or much more likely, in the manual that came with the kid. That DB of monitors in RedHat's configurator only have that information anyway, so when you don't see yours listed it just means you have to go and find out. Somewhere in RH's config toy is where you can set them by hand, if not, you can hand edit the file:
/etc/X11/XF86Config-4
and add them in the "Monitor" section. It'll look something like this:
Code:
Section "Monitor"
Identifier "Display 2"
VendorName "SAM"
ModelName "4f26"
HorizSync 30.0 - 86.0
VertRefresh 50.0 - 160.0
Option "DPMS"
EndSection
