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. and later: > A computational physics code. Ideally I would run it in 100s of GB of > RAM.

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? my $0.02, grant
