[IA64] Updated the generic_defconfig to work with the 2.6.28-rc7 kernel.

The AUTOFS=y and AUTOFS4=y causes problems with some distros versions of
automount.  I turned both of those to =m and then followed the default
prompts for everything else.  I did notice that CONFIG_PNP_DEBUG got
changed to CONFIG_PNP_DEBUG_MESSAGES and the default was a =y so I turned
that back to a =n.
