[2.1.x] AIC7xxx problems

Hello,
I'm having some problems with an Adaptec AHA2940UW SCSI controller in new
2.1 Linux kernels (at least 2.1.59-2.1.63):
The driver doesn't detect my IMS CDD2000 anymore (The other devices
continue to work fine; the CDD2000 works with 2.0.30).
The thing that sets the CDD2000 apart from the other devices I'm using is
that it can't handle Wide-SCSI or synchronous transfers, I guess the
problem is related to this.

Any ideas?

This is the kernel output at boot time (the CDD2000 is at ID 5):
