Hello,
FYI, there is a bug in all(?) 3.x fusion drivers, which prevents it from
working when all the fusion config options are set to 'y'.
It looks like the driver uses schedule_timeout() for delays inside,
which can return immediately on the boot stage and thus drives are not
detected properly.
At least the following verions are affected:
3.03.07
3.02.62.01rh
And according to recent commits it was not fixed since then.
Thanks,
Kirill

There was a patch posted recently that changed all the interruptible
sleeps to uniterruptible sleeps. Here is the post:

Pls retry test with 2.6.17-rc5 + James Bottomely's scsi-misc patch found
