savagefb not working on thinkpad T23 in 1400x1050

[jurriaan]

I got myself a shiny new IBM ThinkPad T23. I've used one for years, and
it worked fine with savagefb and XFree/X.org. The old one had a 1024x768
LCD screen, the new one has a 1400x1050 LCD screen.

Unfortunately, savagefb doesn't work correctly on the new laptop.

X.org works just fine in 1400x1050.

According to lspci, my card is a

Where do I start to look? Has this driver been tested under there
conditions before? I'd really like to get my framebuffer working again,
so I can play Angband without the overhead of starting X :-)

Thanks,

Can you enable debug in fbmon and post your dmesg. Also what default mode 
is it trying to go to?

By default xorg uses the bios to set modes.  Also, most of the panels
on thinkpads run at 50 Hz so you may have to tweak your mode.

I've enabled debug in fbmon and gotten this dmesg (after 'modprobe
savagefb'). I don't see any debug messages. I also don't see any i2c
messages, and there's no *i2c* files under /sys.

I notice I didn't say clearly in my first post that 800x600 works,
1024x768 works, 1280x1024 flickers very badly, and 1400x1050 is
unreadable. Also, X.org tells me it's using a 60 Hz frequency, not 50 Hz
as someone else supposed. A part of Xorg.log is also below.

Thanks for your interest,
Jurriaan
