IBM T30 problems with fxp0, sound and acpi/mouse.

IBM T30 problems with fxp0, sound and acpi/mouse.
I upgraded to 5.0 from -stable and am now trying to upgrade to -head.
I'm testing with the GENERIC kernel and stumble into the following
problems:

Using fxp0 causes timeouts on -head (works fine on 5.0-RELEASE-p7).

    fxp0: <Intel 82801CAM (ICH3) Pro/100 VE Ethernet> port 0x8000-0x803f mem 0xd0200000-0xd0200fff irq 11 at device 8.0 on pci2
    fxp0: Ethernet address 00:09:6b:30:a2:45
    miibus0: <MII bus> on fxp0
    ...
    fxp0: device timeout

These device timeouts render fxp0 useless. On 5.0-RELEASE-p7 fxp0 works
fine, but there are some complaints in dmesg :

    module_register: module pci/if_fxp already exists!
    Module pci/if_fxp failed to register: 17
    module_register: module cardbus/if_fxp already exists!
    Module cardbus/if_fxp failed to register: 17
    module_register: module fxp/miibus already exists!
    Module fxp/miibus failed to register: 17
    can't re-use a leaf (fxp_rnr)!

Sound is not working anymore on both 5.0-RELEASE-p7 and -head (worked
fine on 4.7-STABLE)

    Preloaded elf module "/boot/kernel/snd_maestro3.ko" at 0xc06c00a8.
    Preloaded elf module "/boot/kernel/snd_pcm.ko" at 0xc06c015c.
    ...
    pci0: <multimedia, audio> at device 31.5 (no driver attached)

Enabling ACPI disables the mouse. Without ACPI the mouse works fine:

    psm0: <PS/2 Mouse> irq 12 on atkbdc0
    psm0: model Generic PS/2 mouse, device ID 0

dmesg of 5.0-RELEASE-p7, -head as of now and 4.7-STABLE are attached.

Any hints or suggestions are welcome.
