What's the difference between:
/usr/src/linux-2.6.5-7.111.19 and
/usr/src/linux-2.6.5-7.111.19-obj

It looks like the build procedure is picking and matching kernel parts
from various places in the same build. No wonder it fails.

I'd start tracing from the beginning: /lib/modules/`uname -r`/build and
go from there, see what needs to go where.
