Do Intel chipsets other than the i810 have hardware support for rng/tco drivers
(i845, i860, E7500)? If so will Linux be getting drivers for the tco/rng
capabilities of those chipsets some time in the future? Thanks.

WRT RNG, more than just i810 supports RNG, yes. There are several
chipset ids in i810_rng.c which are for later versions after i810.
So, the driver is perhaps misnamed at this point :) but it's not a huge
deal, so I haven't renamed it to i8xx_rng.c. :)

Do you think I can just add an entry into the rng_pci_tbl[] for my 845PE
(8086, 2560) and have it work?

I don't have the docs, so I'm guessing here, but it's entirely possible.

FWIW, the Intel RNG isn't really in the chipset proper, but rather in
the "firmware hub", the glorified BIOS ROM. The detection mechanism
is interesting, to say the least.
