it may be interesing to try the 2.4.x kernels, especially as later on you
will be able to try other things like journaling and LVM.  If I remember
the USB support was back ported to 2.2.x, this may be an issue but I bet
I'm wrong on this.

I would of thought a PCI refresh would of been called for, if I remember
the pcitweak utility just writes to the PCI buses (or is it BIOS PnP)
memory the settings you want, to then use this you will need a refresh of
the PCI bus for the settings to be applied.

However if I remember this is not a good thing to do on <2.4.x kernels,
the main reason you would want to refresh the pci bus would be if you were
putting your laptop into a docking station, I think on 2.4.x kernels
'like' doing this.  I think you can refresh the bus with pcitweak.

I would suggest looking through the BIOS screen options but if I remember
you boys and girls down at Sony removed the *useful* text BIOS control
thing for 'convenience' :)
