Voluntary Preempt P9 againstclean 2.6.8.1 -- on AMD64, compile failure

On Debian-AMD64
Applied
http://redhat.com/~mingo/voluntary-preempt/voluntary-preempt-2.6.8.1-P9
to a clean 2.6.8.1 (simply copied over my old .config). Patching went fine. Using gcc 3.3.4.

Clean 2.6.8.1, patched with 2.6.8.1

Had to set CONFIG_VOLUNTARY_PREEMPT=y / CONFIG_PREEMPT_VOLUNTARY=y manually in .config. I talked to a guy who said it was there in his "menuconfig". For me the option didn't appear.

Here's my .config: http://findus.dhs.org/~odd/.config

Any idea?

gcc 3.3.4

Cheers.
