Question [Q] HSDPA settings for cooking custom ROM

In want my rom to start with HSDPA disabled.
I can disable it in the settings, but therev seems to be no registry value, that can be set in a custom rom to disable it by default.

Does anyone know, what to do for a custom rom, to get this feature?

I use a B7610 with a custom WM6.5 Rom based on JE2 Build.

Thx
