Generally speaking a "Preliminary" data sheet means that only the sheet is 
preliminary not the device itself.  Looking through the Intel book I notice the 
386SX sheet say's preliminary - this chips been around since 1980's.  If the 
chip wasn't out yet Intel labels the sheet as "Advanced Information".  Sounds 
like it would be worth a phone call to an applications engineer.
