Athlon PSE/AGP Bug

Hi,

The folks at Gentoo Linux have published a news item about AGP related
lockups with PSE on AMD Athlons.

As I have a couple systems that may/may not be affected, I'm seeking
some clarification. Is this an effect of the errata published by AMD in
the Athlon models 4 & 6 revision guides as "INVLPG Instruction Does Not
Flush Entire Four-Megabyte Page Properly with Certain Linear Addresses"?
That errata lists all Athlon Thunderbirds as affected and all Athlon
Palominos except for stepping A5.

Regardless of specific errata listings, will future workarounds be
enabled based on cpuid or via a test for the bug itself?

Regards,
Reid
