It sounds like your board by have the hpd pin polarity reversed (so plug events looks like unplug and vice versa). Please attach a copy of your vbios:
(as root) (use lspci to get the bus id) cd /sys/bus/pci/devices/<pci bus id> echo 1 > rom cat rom > /tmp/vbios.rom echo 0 > rom
Can you also try the attached patch which reverses the hpd polarity?
