What is revised on the motherboard with a new revision? Is this only the bios?

A new BIOS doesn't make a new PCB-revision...new revs will usually include an updated BIOS, but it's Hardware-changes/optimizations that are responsible for the release of a new PCB-rev.

Just as with CPUs, a motherboard-manufacturer will slightly optimize their model during production. This optimization can include minor tweaks of the design, but also the use of a newer stepping of the mobo's chipset - that's when you get a new revision.
For example, the first versions of Asus' A7N8X mobo used an older stepping of the NForce 2 SPP(Northbridge) that did not *officially* support a 200MHz FSB(many of those mobos could still reach a 200MHz FSB, but some did not).
Official support for a 200MHz FSB was added as of revision 2.0 which used the NForce 2 'Ultra 400' chipset(which is merely a newer revision of the old NForce 2 SPP).

This is the reason why a newer CPU is supported 'as of PCB-revision x.x' on many mobos.
The PCB-rev is usually printed somewhere on the mobo itself or on a sticker attached to the mobo.

Oh OK. So obviously newer revisions are preferable, but not entirely necessary depending on what processor you plan to run? Or would they make a difference with certain newer video cards or other components also?

Well, if there were any hardware-related bugs/issues, they might be fixed on a newer revision(not necessarily, tho).

Revisions won't change the features of a mobo(like add USB 2.0 or AGP 8X support or something) - some new/changed BIOS features/options are possible, tho.
