SeaBIOS source code says it has an int13/ah=0x48 implementation:
http://code.coreboot.org/p/seabios/source/tree/master/src/disk.c#L521
(and has supported it for some time), so if you're getting an
error response back then my first guess would be that you're
passing it invalid parameters (eg trying to ask about a disk
that isn't present).
