No.

The "only" difference between the working 2.6.23.8 kernel and the
non-working one is a switch from gcc 3.4.6 to 4.1.2. I've collected
some information about this issue, comparing the 'working' 2.6.23.8
kernel with a newly compiled, patched one. (The unpatched one compiled
with 4.1.2 fails to boot.) So if anybody is interested, have a look at

http://int-e.home.tlink.de/linux/irq/

But it's probably not worthwhile to spend a lot of time on this.
