What type of drivers do they need? Can I use a Pentium heatsink with the ZIF?

none. Unless it's a blue and white, and then you will need to download a firmware update:

the pentium Heatsink will be a bit hard, since the size of the heatsink is a bit awkward for the Zif Socket. I believe the original Heatsink will be fine. It was when I had my blue and white with a 400Mhz G4 in it 😀

Drivers: It depends on the manufacturer. Apple OEM and most Sonnet ZIFs don't need drivers at all, they're totally plug-and-play. The only drivers one might need is the AltiVec code for the G4s, installed automatically with new installations of the OS and software, or installed specially by the manufacturer's utilities.
PowerLogix, XLR8, Newer, and others can require special drivers to enable their L2 caches, in both OS 9 and X. They're usually available from the manufacturer, or from the Internet at large.
As for a PC heatsink, yes, some will fit. However, one must be careful that the heatsink's retainer clip doesn't fit too tight and is installed with the center of pressure over the die of the chip; it's possible to crush the die on those, so one must be careful.
Also, there must be adequate clearance in the case. For example, the G3DT has only about an inch between its stock heatsink and the top of the case. The G3MT has about 1/2" more clearance, and the G3AIO has the most room of all.
B&W G3s and the Sawtooth G4 have less than an inch between their stock heatsinks and the optical/Zip drive setup in their cases, so it's not really ideal to install a larger heatsink in one of those.

Agreed on keeping the original heatsink. However I did run into overheating issues on my Beige, so an additional fan could be useful. I got one of those small, about an inch tall ones from a slot A pentium, mounted it on the side of the heatsink, and was home free from then on.

Just making sure, is the MachSpeed Control a cache enabler?
