The work for XScale happened after 1.1.4 was released, afair. You may 
have more success using the CVS head.

that's some bizarre kernel issue, afaict. It looks like a kernel error 
messages, and it's been discussed here before, as far as I recall. Try 
searching the mailing list archives. I've found

so passing --with-libffi to configure might help fix that issue.
