a hw design
Cool!
- the AT91SAM7SXXX
I'd use a more modern chip that is simpler to work with; something like NXP LPC1343 Cortex-M3 with USB or TI Stellaris LM36432 with 10/100 Ethernet. They're both single supply 3.3V chips. The NXP only needs five-size passive support components.
here the schema : https://file.tsaitgaist.info/www/?a=d&i=CWn6xIaCVe
I get nonsense messages visiting that page. :\ "needs input" something or other. Maybe you can attach them to the wiki?

according to the datasheet VDDPLL powers the oscillator, you should not leave it unconnected. VDDCORE powers the internal logic and is specified as 1.65V to 1.95V.
There might be an internal voltage regulator also for this chip, but I would really go with cm3 for a new design.
