OK, I made this change now.  I tried to reproduce it on one of our
machines, but it turns out that none of them have both memory above
4GB and IDE disks (CD-ROMs don't trigger the BUG_ON).  This also
explains why we haven't seen any problems on our Tiger: even though it
has no hardware I/O MMU and memory above 4GB, it has only an IDE
CD-ROM, not an IDE harddisk.

Thanks,
