We're having some similar issues with our older PowerEdge 1850s 
(DRAC4).  Things were alright on 6.3-RELEASE, but now there is a large 
hangup when trying to install 8.0-RELEASE:

We see ~ 30x of these in dmesg:
   acd1: WARNING - READ_TOC read data overrun 20>12

Followed by this in sysinstall:
   "The disc in your drive looks more like an audio disc than a
   FreeBSD Release" (1).

The DRAC Virtual Media and physical CDROM drives are probed like this in 
dmesg:
acd1: DVR <VIRTUALCDROM DRIVE/> at ata2-slave PIO3
acd0: CDROM <TEAC CD-ROM CD-224E/K.9A>

This is with the latest DRAC firmware available from Dell.
