kde-guidance. It has a configuration utility for X. And according to the 
database (Cards+) that it relies on, it adds the "XaaNoPixmapCache" option 
for exactly to chips:

NAME Intel 810
LINE Option "XaaNoPixmapCache"

NAME Intel 815
# DRI_GLX 16bits
LINE Option "XaaNoPixmapCache"

The pcitable database that guidance uses says that these PCI devices 
are "Intel 810" or "Intel 815":

VendorID DeviceID
0x8086   0x7121   "Intel Corp.|82810 CGC [Chipset Graphics Controller]"
0x8086   0x7123   "Intel Corp.|82810-DC100 CGC [Chipset Graphics Controller]"
0x8086   0x7125   "Intel Corp.|82810E CGC [Chipset Graphics Controller]"
0x8086   0x1132   "Intel Corp.|82815 CGC [Chipset Graphics Controller]"
