Well the PNP ISA/BIOS specs suck.

I can tell you that MS does not enforce those limitations for PNP BIOS or
ACPI nodes.  ISAPNP does enforce those limitations for obvious reasons.

The PnP BIOS spec says (1.0a, beginning of ch. 4.2 at pg. 23):
"Please refer to the Plug and Play ISA Specification 1.0A
(Section 4.6) for the maximum resources that a device node
can use."
Section 4.6 of ISAPNP is where the 4 mem / 8 io / 2 irq / 2 dma
limits are listed.
