Slightly more complicated than that. 32 bit Solaris can use at most 2^31 as disk address; a disk block is 512bytes, so in total it can address 2^40 bytes. A SMI label found in Solaris 10 (update 8?) and OpenSolaris has been enhanced and can address 2TB but only on a 64 bit system. I'm not sure which system uses EFI.
