Some problems on a ThinkPad A30P (again...)

First, a big thanks for the help I got so far (reg. kapm-idled thread)...

Today I've experimented some more, and found the following:

 - even ALSA 0.90beta11 can't solve the suspend problem. I also noticed
   something rather strange, that I didn't realize before (due to
   auto-loading of modules):
        When I try to load "snd-card-intel8x0" for the first time,
        modprobe complains about the card not being found or being
        busy.
        When I try to load the same module a second time,
        everything works "fine"...
   But - WHY would linux at first say, the card isn't there, but
   find and initialize the card on the second run?

 - Due to the problem with ALSA, I went back to try the kernel
   sound drivers instead and found the i810_audio to work fine
   (and - more importantly - not disturb the suspend... ;)
   ("historically" I switched to ALSA on a TP600 which was a pain
   to get sound working with kernel drivers, but which was fairly
   easy to do with ALSA at the time... ...and since then I hadn't
   even tried the kernel drivers any more...)

But - the following problems remain:

 -> Hibernation doesn't work at all (this used to work on the TP600
    and on the TP A21P I had before)...

 -> trying to load agpgart (to make DRI work) fails with:

        Linux agpgart interface v0.99 (c) Jeff Hartmann
        agpgart: Maximum main memory to use for agp memory: 816M
        agpgart: Detected an Intel 830M, but could not find the secondary device.
        agpgart: no supported devices found.

 -> When the system resumes from a suspend, the following message
    turns up in dmesg:

        APIC error on CPU0: 00(40)

    (The system appears to work fine, but I'd still like to know,
     what the error is for...?)

 -> prism2_pci (linux-wlan-ng-0.1.10; linux-wlan-ng-0.1.13pre[1-4])
    WLan throughput is VERY low (~18KB/s, as opposed to ~550KB/s
    on a PCMCIA card, linked to the same Wireless access point;
    also - Win2K also reaches 550KB/s on the internal prism2
    chip)...

Any help on any of the above would be highly appreciated! :)
