Category 3: popular/very common and makes the system more robust

Rationale: having these built in makes the system more robust, also
in case of failure
- ahci (default storage for all new systems; means that there the system
always has the / device driver)
This isn't the default for all new systems -- lots of folks boot off
SCSI/RAID.
- cpufreq_ondemand (means the cpu can slow down for power/thermal)
- acpi_cpufreq (means the cpu can slow down for power/thermal)
Not everybody wants this -- think HPC.
Category 4: VERY popular
------------------------
Rationale: pretty much always loaded in default installs
- snd_seq_dummy, snd_seq, snd_seq_device,
snd_pcm, snd_timer, snd_page_alloc, snd
Completely useless and unwanted on servers/HPC nodes.
It seems that there's an assumption here that Fedora = desktop. While
there's obviously a lot of that, I've seen it on a fair number of servers
and it is a great fit for HPC nodes.
