according to daniel stone, our X god, the X server automatically
allocates a certain amount of shadow ram in the main memory, i dont
exactly know what or how it gets mirrored since i'm not a low level X
programmer, i just can tell from our tests that it happens (ccing daniel
on this mail, since he might be able to clearify). fact is, that if you
put a recent card say a 64MB nvidia card in a low level thin client it
fails to boot if the VideoRam parameter doesnt restrict the amount of
ram ... we tested this on different hardware to come to the conclusion
that the amount needs to be limited for the low memory target we have
for dapper.
