No plans not to, it's just a case of finding the time!

There's also a cy67xxx driver in Grant Likely's PPC Git tree:

http://git.secretlab.ca/git/gitweb.cgi?p=linux-2.6-virtex.git;a=tree;f=drivers/usb/c67x00;h=3aa7749653fb05315e0f0c78f6571e14cd941544;hb=HEAD

Maybe it's the same as the one you saw on linux-usb?

I wouldn't advise forward porting the 2.4 driver, it's a bit of a mess. 
 We ported it to MicroBlaze / PPC linux based on reference drivers from 
Cypress for use on an ARM eval board, but the driver structure is pretty 
messy.

Regards,

John
