There were some problems with inversed signature bytes in the past
(long, long time ago, before avrdude). These were with bad AVR910
firmware it simply returned the bytes in wrong order.

avrdude does not support lock and fuse bytes with AVR910. I made a
small patch that hasn't made it through to the release. Look at the
archives (May 16th, 2003)

Since when does avrdude check the signature before programming?
Are you sure that your AVR910 supports the mega32?

What firmware do you have on your AVR910?
