Also, I find it disturbing that we are forcing users to have know about all these
magic options that have to be put on the kernel boot line. My hard drive on my
new laptop would only run at 1.2mbs until I found out I had to use combined_mode=libata
and build a new ramdisk that included ata_piix.

That's what happens when two drivers want to drive the same hardware. The "slow and safe" default is the only proven-stable option, with the proven-stable PATA driver. The other two options (drivers/ide for PATA+SATA -> leads to SATA locksup) and (libata for PATA -> ok but breaks existing configs, and less field time) are considered less safe.

Combined mode is ugly no matter how you look at it. Just turn it off in BIOS (or pressure system vendor for this ability if BIOS lacks it, e.g. some Dell servers)

And throw some annoyance at Intel for creating such a headache.
