What he said. After some thinking, I loaded up a machine with 3x
SiI3132 and figured I'll expand by port multiplier. Port multipliers
are documented in the standard, not vendor-defined, and are currently
made only by, guess who, Silicon Image. I haven't used any yet, but
apparently they're working, and you know that both the manufacturer and
the linux-ide deveopers have tested them throroughly with SiI controllers.

md0 is the boot partition, md4 is root, and md5 is the main backup data.
Note the way the drives ar arranged on the RAID-10; mirrored pairs are
aplit across different SATA controllers.
