I get this too.  I doubt it's a motherboard compatability problem.
When I use 1152x864x8 I can only get up a couple of small windows.
Enlarging them or trying to create new ones just fails.  Creating
windows with the window command fails with a message something like
"out of resources".  If I run sam on the bare console in this mode, it
often fails with a message about not being able to allocate bitmap
memory.

If I run the system at 1024x768x1, none of this happens, so I assume
it's a memory problem.  However, there doesn't seem to be a shortage of
either real or virtual memory when the allocations fail, so I assume
it's some pool of kernel memory which is being exhausted.  I looked at
the code, but not closely enough to see what was going on.

How does one run a reasonable number of usefully sized windows at high
resolutions?

Details: #9 GXE 64 video card, i486 DX2 66, 16MB memory, IDE drive.
