<< Yes. There are some motherboards that do. However, its not a very consistent list.
Asus: partial yes. KT333 + Nforce board yes; SIS board no; Dual board yes
MSI: partial yes. KT333 yes, Dual board no
Abit: partial yes. KT333 no, Dual board yes
There's a handful of other manufacturers supporting it, but those are the major ones.

Mike: As far as I'm aware, there are only two boards that actually read the XP's internal diode. The Asus A7V333 with it's 'C.O.P.' circuitry and the Soltek SL-75DRV5 with its 'Burn-Shield II' circuitry. Are you positive that there are others out there that do it?
