[K12OSN] Beta 7: i810 and firewall problems

[Petre Scheie]

32MB ram in client

I tried 'X_VIDEORAM = 3072' and got a slightly different error:

xf86MapVidMem: Could not mmap framebuffer (ox44000000, 0x4000000) 
(Cannot allocate memory)

I then tried setting 'XSERVER = vesa' and that DOES work!  Previously, 
setting it to vesa would give me the login screen, but after putting in 
a valid ID & PW, the desktop would never come up.  But vesa seems to be 
working okay now.  Any problems with using that?  For performance 
reasons it presumably would be desireable to use i810; but with only 
32MB, and the iPaq apparently wanting to carve video RAM out of that, 
perhaps that doesn't leave enough for the rest of the system (although I 
recall reading that the memory requirements in 4.2 were less than in 4.1).
