with your fixes there are no oopses  

my g550 experiancies so far:
--------------------------------------------------
everything seems to work pretty OK
as modules, if compiled in the second console didn't
register second vt (or i did somehow missed it?)

but there is a hardware limitation/ problem i think,
and may be matroxfb driver issues

according to dmesg i must be able to use independantly both heads,
but ......
until i use matroxset to swap the matrox's heads, the first VT is displayed
on both heads,
and after i use it both heads are blanked, i can activate the first by a VC
change (ctrl-alt-Fx)
and it's displayed only on one of the heads,
and here comes the problem -- there is no way to activate the second
it remains blank whatever i
try
-------------------------------------------------------------------------------

rivafb seems really broken

in the box with g550 i have two TNT2 M64 PCI 32 Mb,
rivafb reports them as having only 8Mb with/without "nomtrr"
if compiled as module, modprobe rivafb never finishes and eats all the CPU 

in my other box Geforce4 PCI with 64Mb is reported to have !!! 2Mb RAM !!!
