The latter.

Makes sense.

To make things clear: on that machine, there was stock opensuse 11.1
distro kernel which is 2.6.27-based (no b43fcd7dc7b). I needed to debug
a wireless bug, so I kexec'ed wireless-testing (contains 4a865905f already).

So in fact, 4a865905f from the testing kernel triggered a bug fixed in
near past by b43fcd7dc7b.

Did the other two e100* drivers suffer from the same and were fixed
recently? It would render kexec pretty unusable from the older kernels
if this is not going to be fixed anyhow :(.
