If you are running a non PAE, non /3G booted x86 machine,
then, you might try to carefully enlarge the fragment of the session
space used for image mapping, moving it from 8Megs, to 9 or 10 megs.
Don't be creative and try 16 megs first.
Actually, if you cannot get it working with 10 or 12,
I would try a different video card.
By twicking this registry key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory
Management
SessionImageSize = DWORD 0x10
The general theory is the following:
on x86, the session space is statically configured by knonw hard-coded
values
and few overrides from registry.
In the session pace, the portion reserved for image mapping is used by
the display drivers of the system, meaning tsddd.dll, rdpdd.dll, and your
vendor
specific display driver.
ATI is knonw to have HUGE display driver, that are in memory even bigger
than they are on disk, because they use huge zero-initialized data
(AKA, a global array several megabytes big).
If you have etherogenous display drivers, or, for certain configuration
of remote and local display driver, that space may not be sufficient.
If you are running x64/IA64, there are no practical limitation to the
session space.
If you are running /PAE or /3G, then, the system defaults to hard-coded
values,
to preserve functionality.
