Yup, but at least it works for single cards, and that helps a lot of users until radeonfb can do better > Personally I'd just like to ignore the boot VROM and > do everything in the Radeon driver code.

Getting the full POST code is probably a lost cause. However, if you look at the current XFree CVS driver, you'll see rather complete code to get the EDID via DDC/i2c on all connectors.
