xsa and sda are nothing but the device name registered by the driver. It 
is not related to whether the device is a SCSI or not. Since I wrote the 
SysAce driver, I decided to name it as xsa (as opposed to the original 
Monta Vista xsysace). Thus, all the partitions on this device will be 
named xsa1 for the first partition, xsa2 for the second and so on.

When you access your CF card in your Linux PC, the driver names the 
device as sda. Thats all... theres no much difference. Hope you got the 
point.

cheers,
