I was doing the same search when your question popped up (I was about to
write my own toy LM78 driver :-) ... Done a FTPSearch and got lm78.tgz
from ftp://ftp.netwave.de/pub/linux/drivers/ASUS/lm78.tgz
I don't know about the Winbond chip, but from I've read in the Intel site,
the new PCIsets use the HecetaII chip which looks like a stripped down
LM79, with only a I2C bus (instead of the LM78/79 which were accessible
by both I2C and ISA).
The above driver does its job by using the ISA interface. To use the I2C
interface, one has to talk to the PIIX4 chip (which is the bus master).
Since PIIX[4|5] with LM7[8|9]/HecetaII is more likely to be found than a
LM78 at the ASUS-chosen 0x290 address, it looks like it would be a not so
bad idea... /proc/bus/SMBus/... anyone ? (apologies in advance if that's
already been done, I can't check that on the Solaris post office I'm on
right now).
