Both LVM2 and Device Mapper have been updated to accommodate stacking
such a mix of drives.
See this for a bit more detail:
http://people.redhat.com/msnitzer/docs/io-limits.txt
Particularly, the "Stacking I/O Limits" section.
The concern raised for partial (4k) writes to the 512b drive was
discussed a bit more here: http://lkml.org/lkml/2010/2/22/295
