VESA modes inexplicably not available on Matrox p750 ?

[Josh Brooks]

There is a new matrox card (with triple head support) available - the
Matrox Millenium p750.

Forget the triple/dual head features - I have not even loaded X yet - I
just want a reasonable test console mode to do console work in.

Unlike many ATI Rage cards (especially in dell laptops ?) this card does
indeed have full VESA support.

So, my kernel includes:

options		VESA
options		SC_PIXEL_MODE
options		VGA_WIDTH90

but when I boot up, I see this in my dmesg:

# dmesg | grep vesa
module_register_init: MOD_LOAD (vesa, 0xc034e8a0, 0) error 6

So ... thatisnt good.

And when I try to go into theVESA mode, :

# vidcontrol -g 100x37 VESA_800x600

vidcontrol: cannot activate raster display: Operation not supported by
device


So, if I kldload vesa (grasping at the straw here):

# kldload vesa
module_register_init: MOD_LOAD (vesa, 0xc7fb5620, 0) error 6

# kldstat
Id Refs Address    Size     Name
 1    4 0xc0100000 396560   kernel
 2    1 0xc0497000 4a30c    acpi.ko
 3    1 0xc7fb2000 5000     vesa.ko


So I get the error again, but it is loaded as a module.  I try to go
800x600 again:

vidcontrol: cannot activate raster display: Operation not supported by
device


So what is the problem ?  I am ready to have 800x600 console support now,
so this certainly isn't a problem to wait on.

thanks all of you - and let me know if there are addditional data I can
post to you about the problem.
