IMO iSilo is the best bet for reading the SRD on the palmpilot. The free version of iSilo won't be so useful because it doesn't do tables and hyperlinks, but the pay-for version is excellent and well worth its cheap price.
I've got two iSilo versions of the SRD. One is a cut down bare-bones version I did for myself ages ago which doesn't include magic items and is 3e based, the other is from converting the winning entry in the "HTML SRD" competition from some while back - complete, and lots of cross references, but navigation isn't well formatted for a PDA.
They are too big to post up here, but I'll email either to you if you are interested.
(I've also got a d20Modern SRD too)
Cheers
(p.s. what model of PalmPilot have you got?)
