Better only buy motherboards with RS232. Some brands of consumer motherboards
still have 1 port as standard in most models. Configuration may be as
difficult in the kernel as in boot2sio.
Next, try a PCI serial card. These are still relatively easy to find
at a cost of less than a motherboard. Motherboards with PCI slots are
becoming hard to find. (I almost bought a Z87 one with some PCI slots.
3 months later, Z87 is mostly replaced by Z97 and the PCI slots are
mostly gone.)
Next, try a PCIe serial card. These are not so easy to find.

I have one that does work with the keyboard+mouse that it came with.
Apparently, doing the conversion correctly takes a lot of hardware but
incorrect conversions with less hardware sometimes work, an specialized
ones can cut the right corners. Just having the possibility of a
useful conversion requires a PS/2 port on the motherboard. These seem
to be about as standard as 1 serial port. But keyboards with PS/2 are
already hard to find.
