Offhand, I'd suspect that the problem is either interference from
lighting in the room, or perhaps your IR tower is 'marginal'. From your
tests so far it doesn't sound like the problem follows either a specific
computer or an RCX.
Minimize the amount of sunlight since it tends to interfere quite a lot.
Room light (especially from flourescent lights) typically isn't as big a
problem, but you may want to try the test with lights off to see if this
helps.

The RCX was changed slightly, but the ROM is still the same (at least it
carries the same version number and Lego is still shipping the same
firmware for it).

Try running NQC in verbose mode (-v) and sending me the logs for when a
problem happens...
nqc -v -firmware FIRM0309.LGO
You can also try messing with the timeout value to see if it helps (you
specify the timeout in milliseconds rather than letting NQC use its own
adaptive algorithm):
nqc -t 1000 -firmware FIRM0309.LGO
