I did try:

    Dual-Opteron system: Tyan S2885ANRF mainboard, BIOS v2.02
    Fedora Core 2 + recent full yum update
    unpatched kernel.org 2.6.9 kernel
    Mellanox fw-23108-rel-3_3_2
    Mellanox vapi-linux-4.0.1-rc5

If I did not enable MSI-X in the kernel build, all was fine.  If I
enabled MSI-X in the kernel build, mod_thh would fail to load.
