the machine I checked has 5.33, and 5.36 is the date on the sources I 
grabbed in early dec.  the machine in question is running HP XC 3.0, 
based on RHEL4's 2.6.9 - obviously with some backports.

well, afaikt, that's actually a pretty recent sata disk, and certainly
does support SMART.  might you need smartctl -e?  some bioses offer an
option to en/disable smart, but afaikt -e fixed that.

I needed -d ata on my system.  (libata, which has always been intended
to support both parallel and serial - and is now the preferred driver 
for some pata disks...)
