Well, here are the kernel messages from boot.msg.

dmesg output did not work ... there were 200000+  messages like
"[drm:intel_prepare_page_flip], preparing flip with no unpin work?" that
filled the
syslog until X had started up. A really verbose log. It's 1:27 CET, I'll
have to
take a nap now.

BTW: "All the trouble"? Not really. It believe that I have a special
talent to buy the
least supported hardware ... for my previous mobo I had to write a
working framebuffer
driver (cyblafb, now dropped from the kernel), and the PC I used before
that refused
to boot from CD until I hacked isolinux to patch BIOS pointers at
runtime ;-)
