I'm trying to get VESA_800x600 mode to work on my notebook (Toshiba
SatellitePro 445, CT65554 videocard, 2MB, 800x600 LCD), and
unfortunately found that it is impossible. Any ideas of what is wrong?
Following is relevant pieces from dmesg, vidcontrol, kernel debug
(VESA_DEBUG=1 in my kernel config), and trace of syscalls made by
vidcontrol:
