I have just tested the kernel source 2.6.9 from http://www.kernel.org
with the same .config.
No problem, I can have vga=791 and console.
Sorry about not providing further debug info, I only intendend the
follwing as a note that might help.
(The affected machines are not ready at hand, but please ask if more
info is needed)
I did experience this problem using 2.6.9 with a statically built rivafb
module, and
using 2.6.10-rc1 with a statically compiled viafb driver (from patch).
When the drivers are compiled statically and the vga option is given
then there IS a video mode
switch at boot time (wich might come from grub as well which is in
grapnic mode displaying a 640x480 splash)
but the screen remains blank.
If I compile the drivers into a module and boot without the vga option
the drivers initialize
properly when i load them with insmod. (Although they clear the screen
with white, wich is
not a problem, but annoying, and as far as I know this artefact is
present since long time..)
I use vga=0x318, and I give all the explicit mode, depth, refresh, etc
information with a video=viafb:... video=rivafb:... option the driver
can parse
(I looked them up in the kernel sources). I'm sure these options are OK
since they work well
when passed to insmod.
Note: both kernels has the DirectFB fusion patch on them, which is
standalone character device
and im quite sure they do not affect the fb drivers.
Hope this helps. I'm quite fine with using modules, but having the
display properly set from the start of the boot would be nice.
