No... I don't know how to do that. Does you (or anyone else?)

Anyway, if it was an IRQ conflict, wouldn't it show in windows too?
Wouldn't it affect all USB devices? I haven't done IRQ debugging since
~1995!

I Remember changing jumpers to set IRQ in sound cards...

Dapper, I don't know... my BIOS, no. It doesn't really give you much
options except for boot sequence and sony has not released an update
(ever).

Can a firewire and usb mix like that? I didn't know that! I think I need
another adapter from USB to firewire 4-pin to do that.

My model isn't in there exactly, but one laptop from the same series is.
It says USB works, but doesn't give much details. So, it may really not
work (I mean, my usb mouse and pen drive _do_ work, but my ipod and hub
_don't_).

Right now, I posted in the linux-usb-users list and was directed to a
patch that will probably fix the hub. Also, I was directed to enable
CONFIG_USB_STORAGE_DEBUG in the kernel and see if the output can help me
pin point the problem.
