Serverworks AGP problem in 2.4.19

Hi,
 I just tried 2.4.19 with CONFIG_AGP_SWORKS=y on a machine with a
 serverworks chipset, and it wasn't happy.

  Posted write buffer flush took morethen 3 seconds

 gets printed repeatedly ad-nauseum.

 So I'll just turn CONFIG_AGP_SWORKS off, but I thought someone might
 like to know.
