I tried that, with no luck at all...  By doing:

cat /sys/bus/platform/drivers/uvesafb/uvesafb.0/vbe_modes

I see that 1920x1200-32 corresponds to 0x017d.  I tried to specify
that with vbemode option, several ways, like keeping the 1920x1200-32
option, removing everything but the vbemode option, etc...  And the
result is always the same128x48...

Thanks,
