It's not a lame question. It's a good one.

Yes-= for SIMs that can call xpt_rescan. That would be isp && mpt. It 
would apply, btw, also for MPT/SAS.

We already have an 'adequate' mechanism for noticing that a drive has 
gone away. The AC_FOUND_DEVICE doesn't work like you'd expect. It's 
possible that this just needs to be fixed (to use xpt_rescan :-)).
