Ironwood Electronics has these nice parts. Not sure which one is suited best for a "remote bios flasher".

Can they be used at all? Or will applying power to the pins do weird things to the board (missing pull up resistors or something?)

I guess this is the component you mentioned to me earlier. Since the mainboard is prepared for dual bios chip, there must be the circuitry to deactivate CHIP SELECT for the individual chips or sockets. It should be a poss to revive dual bios with that clip adaptor. --Q

I like SMT. It's also the lowest of them.

It depends on what the flash is connected to. E.g. LPC clock will be an output from the chipset, It's not safe to assume that it will be in high-impedance state when power is applied to the 3V3 rail used by the flash chip since the same rail may be used by the chipset, causing the output to be driven either high or low.
Driving the signal low or high exernally will then cause a short circuit in the chipset output driver for that particular signal, possibly killing it depending on the current.
Some drivers have good protection against shorts but I don't know if it's common enough to be assumed.
