The aic7xxx driver does not spit out any messages at all.  Here's what I
get, after the IDE cdrom and floppy disks are detected:

   Partition check:
   request_module[block-major-8]: Root fs not mounted
   VFS: Cannot open root device 08:01
   Kernel panic: VFS: Unable to mount root fs on 08:01

Embedded AIC-7896/7 found on Intel-produced L440GX motherboards.  Here's
what dmesg produces, using the 6.1.13 driver:

Here you go.  Some of this is going to wrap.
