Copy the "alps_bsrv2.c" and "compat.h" from the DVB-tree to "build-2.4"
Attached is a errorfree compiling diff against dvb-kernel from today
witch revivals the old alps_bsrv2 frontend driver.
If you want to use it, don't load the "ves1x93.o".
For me it works pretty realible (tested with a few hundred channel
switches).
