AFAIK the only 2K/XP spesific API call D3 and Q4 use is
"GlobalMemoryStatusEx".  The 9x version is "GlobalMemoryStatus".  Is the
case of running Doom 3/Quake 4 there is no pratical difference between
the two calls.  From what I have heard "GlobalMemoryStatusEx"  can
address up to 4TB of memory but "GlobalMemoryStatus" can't.

Valid point in some cases, not however for D3/Q4.

"GlobalMemoryStatusEx" must not be very critical because
"GlobalMemoryStatus" seems good enough to run D3/Q4, and I have run Q4
on WinME with 512MB ram and a GeForce5200 with 128MB ram and it was
still playable and it NEVER crashed on me.  D3 only locked up ONCE for
about 5 seconds as it had to wake up the HD, and that was running a
Geforce4 MX440 with 64MB ram.  Both times were on a AMD Athlon XP 3000+.

I don't get what you mean with that.

The bottom line is that Doom 3 and Quake 4 will run perfectly well on at
least WinME and I have read reports of D3 running on 98se.  IMHO there
was no real good reason to exclude 98/ME systems.
