Yes, the CDROM was connected to the Marvell based PATA port.

That should not make a difference as the kernel isn't yet loaded.
It's all within the loader operating through BIOS calls (?).
It looks like the Marvell ATA BIOS upsets the loader when booting
from one its drives.

When reconnecting the CDROM to the nForce based PATA port the loader
doesn't crash anymore and the kernel begins to boot until this:

atapci0: <nVidia nForce MCP55 UDMA133 controller> port 
0x1f0-0x1f7,0x3f6,0x170-0x177, 0x376,0xf400-0xf40f at device 12.0 on pci0
ata0: <ATA channel 0> on atapci0
ata0: [ITHREAD]
ata1: <ATA channel 1> on atapci0
ata1: [ITHREAD]
acd0: DVDR <PIONEER DVD-RW DVR-103/2.00> at ata0-master PIO4
acd0: FAILURE - READ_BIG MEDIUM ERROR asc=0x11 ascq=0x06
GEOM_LABEL: Label for provider acd0 is iso9660/FreeBSD_Install.
acd0: FAILURE - READ_BIG MEDIUM ERROR asc=0x11 ascq=0x06

then it just hangs (not hard though)...  Have tried it with two
different CDROM drivers from different makers with identical results
(the other drive is a plain Toshiba DVDROM).  Image is FreeBSD 7.0BETA3
AMD64 burned to a CD-R. Exactly the same problem with BETA3 i386.
FreeBSD 6.2R i386 boots into the installer successfully.
