IRQ problems on new Toshiba Libretto

Hi there!

I am trying to install Linux 2.4.4 on the new Toshiba
Libretto, the one with the Crusoe CPU, 1280x600 screen,
1kg (I think it is currently only sold in Japan).

I am having problems with IRQs and the recognition of
system components, which I suspect is the reason, why
about half of my devices are unusable. I am getting the
message "PCI: No IRQ known for interrupt pin A of
device 00:00.0. Please try using pci=biosirq." This
message is repeated for the following devices:

00:00.0 Host bridge: Transmeta Corporation LongRun Northbridge
00:06.0 Multimedia audio controller: Acer Laboratories Inc.
00:0f.0 FireWire (IEEE 1394): Texas Instruments: Unknown device 8020
00:10.0 IDE interface: Acer Laboratories Inc. [ALi] M5229 IDE (rev c3)
00:12.0 CardBus bridge: Toshiba ToPIC95 PCI to Cardbus Bridge
01:00.0 Ethernet controller: DECchip 21142/43

I have put the details of /var/log/messages, lspci, /proc/pci, 
pnpdump and the kernel configuration into the file
http://launchers.tripod.com/linux/libretto_logs_n_kernelconfig.txt

I searched the mailing-list archives for this error
message for the last days, applying suggested kernel
parameters and kernel-patches, but without success.
Unfortunately the Libretto seems to have no common
BIOS - didn't find how to enter and change anything
- - all settings are done from Windows :-(

Now I have a number of problems, which I suspect are a
consequence of the above error message:

o   PCMCIA cards are not initialized and return the
above error message (for device 01:00.0) when inserted.
Therefore I can currently not use any PCMCIA device 
(modem, ethernet, CD-Rom !!!) - THIS IS CRITICAL!

o   ACPI output is bogus, showing a remaining battery
capacity, which jumps every few seconds to levels
somewhere between 0 and 100%. The Librtto only supports
ACPI. I am using version acpi-20010518 patched
against kernel 2.4.4, so it should be up-to-date.

o   I can not find my internal (win)modem. Neither
lspci -vvv, pnpdump nor /proc/pci give any evidence
- - but the modem works fine under windows - I mean it is
really there.

o   I fail to initialize the ASLA-sound module for my
ALi-chip (same error message). 

At the moment the core system (CPU, memory, harddisk,
screen and keyboard) is working well. But I would like
to make the whole system work properly - just don't
know what else I can do. I'm not a kernel hacker. Can
anybody help?

THANKS!
Aron
