Windows 7 64 bit on Mac Mini ... not all happy joy joy

Since my MacMini has 8Gb of memory now, I thought it didn't make sense to continue using 32 bit Windows.  So I went ahead and install Windows 7 Ultimate 64 bit on the Windows partition in Mac Mini.  Trouble started since then.

First I found that the Canoscan driver and Canoscan software failed on Win7 64 bit even though the driver and app was installed properly and being recognized.  And then I found that the bluetooth mouse was not being recognized, even though the hardware itself was working great, and had no problem on the Mac side.

And then more shit happened.  After I installed VMWare Server 2.x, Wacom tablet stopped functioning.  That totally pissed me off.  UNinstalled VMWare Server and things seemed to get back to normal.

That's not the end.  I also found out that the Mac Paritions on my 1.5Gb harddisk was GONE after being touched by the Windows 7 disk manager.  Well, if I didn't make a stupid mistake, I may still be able to restall that parition since after I switch back to the Windows side, I can see the partition.  Too bad I made one dumb more and now everything is gone and I have to start from scratch.
