ECS A740GM-M with ATI RADEON 2100 sends data to i2c bus
for a DVI connector that is not implemented/existent on the board.
Fix by applying extented DDC probing for this connector.

Log PCI subsystem vendor and subsystem device ID in addition to
PCI vendor and device ID during kernel mode initialisation. This helps
to better identify radeon devices of third-party vendors, e. g. for
bug analysis.

Some integrated ATI Radeon chipset implementations with add-on HDMI card
(e. g. Asus M2A-VM HDMI) indicate the availability of a DDC even
when the add-on card is not plugged in or HDMI is disabled in BIOS setup.

Provides function drm_edid_header_is_valid() for EDID header check
and replaces EDID header check part of function drm_edid_block_valid()
by a call of drm_edid_header_is_valid().
This is a prerequisite to extend DDC probing, e. g. in function
radeon_ddc_probe

Dear Dave,
Alex asked me to send you the updated set of proposed kernel patches for
extended
DDC probing in kernel radeon driver. The patch is based on Linux 3.0-rc7.
The patch code itself is exactly the same as in
