Subject: * added support for letting plugins suggest additional kernel modules
 * used this new functionality in the theme and vmware plugins to suggest  
 the kernel modules they need (this should fix showing the console in ubuntu)
 * added distro-specific kernel module filtering, such that there no longer
 are   the spurious warnings about 'hid', 'unix' and/or 'af_packet' not being
 found
