2.4.8-ac8 works for me, and lspnp does list these "obscure"
ressources:

bytesex kraxel ~# /root/bin/lspnp -v
00 PNP0c01 memory controller: RAM
mem 0x00000000-0x0009ffff
mem 0x00100000-0x0bfdffff

03 PNP0000 system peripheral: programmable interrupt controller
[ ... more standard PC hardware follows ... ]

But it seems they are _not_ reserved by the pnp bios code, at least they
are not listed in /proc/ioports

Why? It shouldn't harm if disabled, so IMHO it should be fine when
flagged "experimental" and with a warning label about broken bioses in
Configure.help ...
