There's no such thing as 82801EP as far as I know. According to the
lspci output below, I'd say it is an 82801BA (aka ICH2).

Hmm, 2443? ;)

This is a known problem. BIOS hides the device. See in prog/hotplug,
there's p4b_smbus.c, README.p4b and Makefile.p4b. You need to use this.
Move there, "make -f Makefile.p4b", install and insmod module
p4b_smbus.o. Then you should be able to use the i2c-i801 driver.
