OK, it worked.
This is what I did:
make ARCH=i386 INSTALL_MOD_STRIP=1 olpc_defconfig
make ARCH=i386 INSTALL_MOD_STRIP=1 menuconfig
there, I activated bluetooth
make ARCH=i386 INSTALL_MOD_STRIP=1 modules
make ARCH=i386 INSTALL_MOD_STRIP=1 modules_install
modules compiled and ?worked?
well, it seems I need /usr/sbin/bluetoothd provided by bluez,
but there's no bluez package avaiable, so I'll try to compile
the source code and see what happens...
I'll tell you whether I succeeded or not....
