    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
    mem 0x0bfe0000-0x0bfeffff
    mem 0x000e0000-0x000fffff
    mem 0xffff0000-0xffffffff
    io 0x0398-0x0399
    io 0x0024-0x003d
    io 0x0062-0x0062
    io 0x0066-0x0066
    io 0x0090-0x009f
    io 0x00a4-0x00bd
    io 0x0230-0x0233
    io 0x1000-0x103f
    io 0x1400-0x140f
    io 0x3810-0x381f

    01 PNP0c02 reserved: other
    io 0x0cf8-0x0cff
    io 0x04d0-0x04d1

    02 PNP0c04 system peripheral: other
    irq 13
    io 0x00f0-0x00ff

    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 ...
