Hi,

1. The problem is I don't remember exactly which kernel was used when monitor
was properly recognized by HDMI/DP. I've checked several kernels (from official
kernel.org and using debian's one.) and none of them was working:
- vmlinuz-2.6.39.4
- vmlinuz-3.1.10
- vmlinuz-3.2.0-3-amd64
- vmlinuz-3.2.48 (?)

2. But I've discovered a difference in dmesg output when plugging/unplugging
hdmi cable if we compare 3.1.10 and 3.2.0-3-amd64 (debian's) kernels.

Scenario is the same as previously:
0. Setup TV (hdmi) and boot the system + dmesg
1. plug hdmi + dmesg
2. unplug hdmi + dmesg
3. plug dp + dmesg
4. unplug dp + dmesg

#Size output
72089 dmesg_3.1.10_0_hdmioff_dp0off
85601 dmesg_3.1.10_1_hdmion_dp0off
85601 dmesg_3.1.10_2_hdmioff_dp0off
86926 dmesg_3.1.10_3_hdmioff_dp0on

87276 dmesg_3.2.0-3-amd64_0_hdmioff_dp0off
87276 dmesg_3.2.0-3-amd64_1_hdmion_dp0off
87276 dmesg_3.2.0-3-amd64_2_hdmioff_dp0off
88601 dmesg_3.2.0-3-amd64_3_hdmioff_dp0on
