Eugene, could you please try adding:

options sdhci debug_quirks=1

to a new file named /etc/modprobe.d/sdhci-quirk.conf and rebooting?
Please include `lspci -n` and `dmesg` output in your reply.

It would also be useful to know whether you see the same problem when 
booting (say) a Fedora 13 livecd, since the link below claims that 
Fedora doesn't share this bug:
