Hallo,
Bei 32 Bit Applikationen klappt es via WOW-Subsystem in vielen Fällen mit der Abwärtskompatibilität. Bei Hardwaretreibern sieht es leider nicht so gut aus:

"32-bit drivers
The x64-based versions of Windows Server 2003 and of Windows XP Professional x64 Edition do not support 32-bit drivers. All hardware device drivers and program drivers must be compiled specifically for the x64-based version of Windows Server 2003 and of Windows XP Professional x64 Edition.
If a 32-bit program tries to install a 32-bit driver on a computer that is running an x64-based version of Windows Server 2003 SP1 or of Windows XP Professional x64 Edition, the installation of the driver fails. When this behavior occurs, the x64-based version of Windows Server 2003 SP1 or of Windows XP Professional x64 Edition reports an error to the 32-bit program.
If a 32-bit program tries to register a 32-bit driver for automatic startup on a computer that is running an x64-based version of Windows Server 2003 or of Windows XP Professional x64 Edition, the bootstrap loader on the computer recognizes that the 32-bit driver is not supported. The x64-based version of Windows Server 2003 or of Windows XP Professional x64 Edition does not start the 32-bit driver, but does start the other registered drivers.
To determine whether a program requires a 32-bit driver, install and run the program. If the program generates an error message, contact the manufacturer of the program for an update that is compatible with the x64-based versions of Windows Server 2003 and of Windows XP Professional x64 Edition."
Der Artikel spricht zwar von der XP-Linie, es ändert sich IMHO aber auch bei Vista nichts in der Sache.
Gruß,
Michael
