I believe the number was limited to 15, due to limits in a certain
proprietary operating system.

The issue with the AML code in BOCHS vs the code in Seabios is a bit
tricky. The tables in BOCHS are a fair bit more complicated with the
hotplug code and therefore statically generated, whereas Seabios
generates them dynamically at boot time.

Generating the more complex tables dynamically would be preferred, but
it requires like half an AML compiler in Seabios, so it kinda stalled
there....
