CentOS - Aug 2008 - udev rules for /dev/sd[a-z] ?

I have a third party application that I want to run a CentOS4 box that 
is expecting to access the generic SCSI devices through /dev/sga, 
/dev/sgb, etc. However, the devices set up by udev are /dev/sg0, 
/dev/sg1 etc.

Does anyone know what syntax I could use to create a udev rule that 
creates symlinks sga -> sg0 etc. for each sg[0-N] device?

Thanks

just curious, what sort of scsi controller is that?   every CentOS 4 
system with regular SCSI (or SAS or whatever) that I've seen has created 
/dev/sda /dev/sdb, etc...   only exceptions I've seen are are things 
like Compaq/HP SmartArray controllers that use /dev/cciss/c0d0
