The Win7 gang missed out the fact that people actually use wireless networking devices. A quick look at their website confirms that of the 'incompatible' hardware, wireless adapters and routers are the number one issue (most are not yet certified).
Normally 64 and 32 compatibility will happen together. You might want to submit a bug report to M$ and ask your manufacturer for a recommendation, though I suspect they will ask you to buy a new laptop. They may be able to offer a compatible module for wireless though, and in the long run that may be less painful unless you are willing to wait for the driver teams to get their act together.
If, that is, they are actually working on it, of which I have my doubts.
