In 2.4.19-rc3-ac2, Alan Cox / James Mayer added a modeline entry to
modedb.c that enables a 1280x600 console screen on Vaio C1M* devices.
The patch works fine for me in 2.4.19.
In 2.4.20-pre* kernels, it does no longer work for me, the console
remains at the default setting.
I identified the hunk below to be the culprit. That check was removed in
2.4.20-* kernels. When I revert the hunk below, adding back the null
check, my system again switches to full screen console mode.
I propose to revert the hunk for 2.4.20.
Tested with 2.4.20-rc1.
Thanks,
Kai

This "According to XFree86 4.2.0..." patch was never in the 2.4 tree. It
is in the -ac tree (the latest -ac kernel is 2.4.20-pre10-ac2).
It might be a good idea to add it in 2.4.21-pre to the 2.4 tree but it's
most likely too late to get it into 2.4.20.

For what it's worth, Ani Joshi was going to add it in the next
radeonfb 2.4 version...
