Aha. Small PC? No separate graphics card, but a VGA connector built into
the motherboard? This almost certainly means the video chip doesn't
have its own memory array and is using main memory, and this may
need to be set up in the BIOS.
Scratch that. Before you do anything else, run lspci from the command
line and write down the part number for the VGA controller, then Google
for that and XFree86. See if this is a well known problem.

24-bit colour is usually actually 32-bit colour - 4 bytes per pixel. You
can work out from that the amount of raw memory needed to hold the
image planes. The catch is that the X server usually wants some extra to
use as temporary image storage. Your big glowing hint here is that the X
server wants 6 MB....
