In my case it says:
package preload-kmp-default is not installed
Actually, even if I try to install it, there is no package for 3.0.1 kernel.

OK

OK, maybe Fajar is very busy in this days. No pressure for him! :)

OK, this is what I see right now (without any change):
stdvga=0 && videoram=16 && kernel 3.0.1
Region 0: Memory at f0000000 (32-bit, prefetchable) [size=32M]
Region 1: Memory at f3020000 (32-bit, non-prefetchable) [size=4K]
Max Resolution: 800x600

stdvga=1 && videoram=8 && kernel 3.0.1 (I noticed the domU is slightly faster)
Region 0: Memory at f1000000 (32-bit, prefetchable) [size=8M]
Expansion ROM at <unassigned> [disabled]
Max Resolution: 800x600

stdvga=1 && videoram=16 && kernel 3.0.1
Region 0: Memory at f0000000 (32-bit, prefetchable) [size=16M]
Expansion ROM at <unassigned> [disabled]
Max Resolution: 800x600

stdvga=1 && videoram=32 && kernel 3.0.1
Region 0: Memory at f0000000 (32-bit, prefetchable) [size=16M]
Expansion ROM at <unassigned> [disabled]
Max Resolution: 800x600

So, something changed for 8 and 16M! But I didn't understand what has
changed. Now the
"size" increases but the max resolution is still 800x600. At least I notice
a faster domU with these settings. Haven't we already tried to set different
videoram quantity in our previous attempt, without success? Maybe the
only attempt we did was for videoram=32.

Thanks a lot!

Flavio
