way would be to always reserve that page, but I didn't feel like punishing everybody just for a hardware bug in a single chipset.
Patch for 2.5.53. Please consider applying.

That's the wrong way to do it. Workarounds like this need to be automatic, and with init code sections, there is no excuse not to. Instead of making the user pass a quirk option, why not reserve the page and then free it if the errata is not present?

That's exactly what I suggested to Andi in private mail and he said "yes, this would work". So I expect a patch doing exactly this from him. :-)

(Yes, I could have done it myself but I have neither the chipset or am I a deep innards kernel hacker).

Regards
Henning
