Booting with: vga=normal no387 nofxsr
gets me no forther.   These are all the messages I get:

boot: 2.6.18rc7git2 vga=normal no387 nofxsr
Loading 2.6.18rc7git2...................................
BIOS data check successful
Uncompressing Linux... Ok, booting the kernel.

And then the system hangs and requires a power cycle.

So unfortunately that does't help much :-(
