Unknown Manufacturer Unsuported Device

XP Pro SP2

I have previously used the above device type to provide support for Minolta
Dimage Scan Dual Film Scanner, once installed as this device type the
associated software can find and use the scanner, I have done this many
times on Intel based machines under W2K and XP Pro & XP Pro SP2

I have recently purchased and AMD64 based machine and installed XP Pro and
the driver type no longer exists, it is also missing after installing SP2,
is this device type only available on intel based PCs or has it been
withdrawn form current XP distributions ?

Is there a way arround this problem ?

Thanks
