    Few other drivers have the potential to turn a perfectly functioning £3000
    laptop into a useless heap of plastic and metal in less than a millisecond.
    I have six different Toshiba's to hand and had intended to test my 2.4 patch
    on all of them before submitting my 2.4 version of the driver.

    Indeed apart from the #ifdef's I was using your patch is essentially

    Is there any specific advantage, it's only used to grab some BIOS info
    during the driver load.

    When I wrote the driver the intention was to be nice and claim and release
    my ports properly. The problem is other drivers are claiming ports that
    are not there's to claim. For example on the machine I am typing this
    port 0xb2 is claimed by pic2. Now in reality pic2 can never be using port
    0xb2 as this would reek havoc on Toshiba laptops, and a normal Linux kernel
    does not have problems that would be evident if it was using port 0xb2.
    I suppose the question is why is the pic2 driver claiming ports that are
    not it's to claim. The same goes for the keyboard driver as well.

    Give this the code to claim and release ports is in a sort of limbo until
    I could figure out what the right thing to do was.
