PCI resource conflicts in recent 2.4 kernels

I'm running Redhat 8.0 on a docked Toshiba Tecra 730CDT (Pentium 150MHz, 80MB RAM), and recently tried to upgrade my kernel to one of their errata kernels. When I did, I got PCI resource conflicts, and the SCSI devices are unable to initialize. Partitions are not mounted, so the boot fails. I confirmed that the problem also occurs with the latest (2.4.21-pre3) vanilla kernel. Originally reported to Redhat:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=76159

I was unable to find any similar report via google searches, but there are a couple of recent similar reports in the Redhat buzilla (bugs 78035 and 76428).
