[Linux-fbdev-users] radeon/2.6.5-rc1-mm1 sets strange frequencies

[Jurriaan <thu...@xs...>]

[this was meant to go to linux-kernel and fbdev-users at the same time,
but I made a typo. sorry]

After booting 2.6.5-rc1-mm1 with this command-line:

kernel /vmlinuz-265rc1mm1 root=/dev/hda3 video=radeonfb:1600x1200-32@75 acpi=force

I get a warning on my monitor:

fH 271.5 kHz
fV 217.2 Hz

That is obviously not what I meant by 1600x1200-32@75.

fbset -V tells me:

.config:

Obviously, it's bad that I define what video-mode I want and radeonfb
starts changing that to bogus values. The monitor is an Eizo F931,
connected via a Rose Electronics Vista KVM.

Any hints on solving this?

Thanks,
Jurriaan
