Subject: Makefile Automatically enabling Zaptel MMX support. Disabled by
 default for now. * To enable, build with ZAPTEL_MMX_AUTO=yes (or any other
 non-empty   value) * There is a white list of configuration values (without
 the prefix   CONFIG_). One of them needs to be set in order for
 CONFIG_ZAPTEL_MMX   to be enabled. * Only adds support for kernel 2.6 . If
 anybody finds a simple way to do   the same with 2.4 - patches are welcomes.
