Of course.  The 7500 datasheet is available at:

Lots of datasheets links (all the major chips) and schematic at:
http://www.geocities.com/webpalstuff/

Quite a bit slower than the StrongARM, but it does have a floating point
coprocessor.  Don't know if anyone is using it or how well the FPA is
supported by gcc, linux, or netbsd, however.

I think it would be fun to pipe audio over ethernet to it.  Use the Webpal
as a buffer and DAC, and a beefier back-end machine to convert from
whatever file format (MP3, uncompressed 44.1k/16 bits, whatever) to raw
audio samples and stream it out.
