Hi Ingo,
I gave 2.6.18-rt2 a quick try. It compiled fine but crashed on
boot.

Hi again Ingo.
2.6.18-rt3 booted. For some reason a number of drivers either
didn't get built or didn't get loaded. I'm looking into that now:

lightning ~ # lsmod
Module Size Used by
lightning ~ #

I am wrting you from the machine running the new kernel so we're
making headway.

I spot this in dmesg though:

EXT3-fs: mounted filesystem with ordered data mode.
Adding 2008084k swap on /dev/sda10. Priority:-1 extents:1 across:2008084k
eth0: no IPv6 routers present
BUG: time warp detected!
