I had already tried that... it locks up at the same point also with
"enable_msi=1".
tindog:/etc/modprobe.d # less 50-sound.conf

options snd slots=snd-hda-intel,enable_msi=0
# mDsH.vLXC8EvZgR7:MCP55 High Definition Audio
alias snd-card-0 snd-hda-intel

The motherboard giving the problem is the Asus M2N32-SLI deluxe.
00:0e.1 Audio device: nVidia Corporation MCP55 High Definition Audio
(rev a2)

No such problem with the Asus CROSSHAIR II FORMULA motherboard which
also has the
00:07.0 Audio device: nVidia Corporation MCP72XE/MCP72P/MCP78U/MCP78S
High Definition Audio (rev a1)

For any kernel >2.6.32-git1 it hangs, i.e 2.6.32-git2 to 2.6.33-rc5.
Disabling the sound chip in the BIOS, they all boot.
tindog:/etc/modprobe.d # uname -r
2.6.32-git1-smp
tindog:/etc/modprobe.d # l /dev/dsp*
crw-rw-rw- 1 root audio 14,  3 Jan 26 11:46 /dev/dsp
crw-rw-rw- 1 root audio 14, 35 Jan 26 11:46 /dev/dsp2
