I've tested the e1000 (4.0.24-k1, iirc) driver on HP's "2cd generation
Intel (r) Itanium (tm)" systems and it basically works. Based on
this, I would expect this e1000 driver to work on A500-like systems.
(ie rp24xx boxes). Someday, if i get the itch, I'll plug one into
my a500 and try it.

The approach seems really odd - you are looking at 64-bit userspace so
you can *swap* large amounts of virtual memory in/out. If you expected
to be IO bound, tuning the app to know more about IO (instead of
swapping) makes more sense.

Have you tried begging, trading, or buying some cycles on a Superdome
with some 100GBs of RAM instead of waiting for weeks to see your jobs
run to completion?
