Looks like a pci/acpi-issue with your toshiba. the kernel can't find a 
useable irq for the yenta bridge. sometimes you can fix this with
bios-entries, but i don't know the 2100. does the 2100 has a phoenix or
a toshiba bios?

If acpi is enabled on your lappi try to switch it off. If it's disabled
try to enable it. use a kernel command line like acpi=off at the

linux acpi=off

However, acpi is quite useful for laptops.

As the above dmesg output suggests you should try .. 

linux pci=biosirq
linux pci=usepirqmask

..also. yet, i havn't seen this working.  

There are various other acpi-pci options you might try to get your 
IRQ-routing right. Have a look into kernel-parameters.txt from the 
kernelsources' Documentaion tree.

btw. I have a WG511t and it's equiped with an atheros (madwifi) chip.
