Until now you could get NET CF3.5 as default only if you cooked it into a ROM. But I've found the registry setting that can disable the default net CF 2.0 and enable net CF 3.5 as default. There is a noticable increase in speed and it shows on the benchmarks as well. I used to get 1320 on mine now I'm getting 1499 with VBenchmark.
What you need to do:
1. Install NetCF3.5 on your ppc.
2. Open a registry editor, I use Reso Regsitry Editor
3. Goto HKLM\Software\Microsoft\.NETCompactFramework (this is usually the first entry
4. When you open this you'll see all the .NET installed version change the DWORD value of 2.0.7045.00 from 1 to 0
5. Change the DWORD value of 3.5.7283.00 from 0 to 1.
6. Reboot
7.Viola! you have a faster PPC
