Problem with 10.4.8

I was having some sort of wishful thinking that using MacOSX 10.4.8 on my Tablet PC may be allow me to achieve holy grill experience with Mac OSX. Specfically, I was hoping that the following will work after I put in 10.4.8:

• Tablet Digitizer
• My external USB based WiFi adapter

So I tried, and failed. Neither of them were being recognized. And by then I was not even bother to try Firewire Solo driver anymore for there's no point to try it afterall if I am not staying with 10.4.8.

So now I have restoring the Mac 10.5.1 from a saved partition. Thanks to Acronis True Image 10, I can switch between OSX without the need of manually reinstall tons of drivers and settings and apps.
