We got it working by copying firmware from another system (FC8) that had
it in /lib/firmware.

Just retested with -rc8 from Friday, and it is repeatable.

The config & dmesg is attached.  Some of the options are for patches we've
added, and we even have a small patch in the e100 (but have had it there
for years, so probably un-related to this).  Still, I will not complain
if you decide to ignore the report.
