I doubt your problem is hardware.  My system is similar to yours:
Athlon XP 1800+, 256MB DDR, EIDE disk, M-Audio Delta-66; yet it runs
JACK reliably down to about -p64 (even -p32 but with some overruns).

Check your hdparms.  But, most of all I recommend making sure you're
running the low latency kernel patches.  This is essential.  The JACK
FAQ has some useful instructions...
