Michael,
You might want to try out Andrea's alpha bigmem patch:
ftp://ftp.kernel.org/pub/linux/kernel/people/andrea/patches/v2.2/2.2.14/bigmem-2.2.14-7.gz
I just installed it my ES40, and it sees 4 gigs of memory:
[ezolt@cpu98 /tmp]$ free
Unknown HZ value! (4096) Assume 1024.
total used free shared buffers cached
Mem: 4101872 490184 3611688 743152 21896 374288
-/+ buffers/cache: 94000 4007872
Swap: 129016 0 129016
Cheers,
--Phil
