Yes it is.

Whew, finally solved this problem. 1600 x 1200 32-bit color is now working
with the Win7 in-box ATI driver. The problem is that some important
information is passed from coreboot to the ATI video driver, and some of
it was incorrect. The information is passed by placing it in the last
512 bytes of the frame buffer, so it is easy to look at. The format of
the information is in struct ATOM_INTEGRATED_SYSTEM_INFO_V2.

I should have thought of this when the slow HT link problem resulted in
screen tearing. The driver tries to never let this happen. One of the
items passed to the driver is HT link frequency and width. Hard-coded
values were used for link frequency and width, and frequency was invalid.
Apparently the driver skipped the bandwidth checks because of this.

I believe with this change, Win7 will be able to get through setup

[commit] r6004 - trunk/src/mainboard/asus/p2b-ds

Author: uwe
Date: Sat Oct 30 23:27:13 2010
New Revision: 6004
URL: https://tracker.coreboot.org/trac/coreboot/changeset/6004

Log:
Mptable related fixes for ASUS P2B-DS.

 - Add "select IOAPIC" in the board's Kconfig file.

 - Set CONFIG_MAX_PHYSICAL_CPUS to 2 on the board. There are two
   CPU sockets (Slot 1) and each CPU can only have one core, multi-core CPUs
   didn't exist in that era (CONFIG_MAX_CPUS was set to 2 already).

 - Drop useless/duplicated enable_lapic() call from ASUS P2B-DS's romstage.c,
   that function is always called if either CONFIG_SMP and/or CONFIG_IOAPIC
   are set.

 - Rework ASUS P2B-DS mptable.c to fix a number of things:

   - Convert it to use mptable_write_buses() as all mptable.c files should do.

   - Fix incorrect IOAPICID (it's 0x11 for the external 82093AA IOAPIC).

   - Fix a bunch of hardcoded bus IDs, remove incorrect entries, etc.
