New status:
Working:
- memtest86 works for 2 GB RAM
- FILO works and loads a Linux kernel
- Linux boots
- SATA disks work under Linux
- Network works under Linux
- Power button works
- Software poweroff works
Untested:
- VGA analog/DVI because I have no monitor available right now
- USB (later)
- SeaBIOS
Probably not working, must retest:
- 4 GB RAM
Not working:
- SATA multicount transfers (detected as unsupported by Linux)
- Powernow ("invalid freq entries 1000000 kHz vs. 800000 kHz")

Patch against AMD DBM690T follows. Most parts of the patch (those for
generic code) have been submitted already.
