The SGB boot ROM inside the Game Boy portion transmits the Nintendo copyright logo for bootup verification, but that is it.
Also most of the GB ROM "header" (or information sector or whatever), if I might add.
Thus, the SNES is able to determine name, mapper etc. of the inserted Gameboy game.

How well does the SGB tolerate pak swapping?
Very.
Pulling the GB cartridge while it's running will of course crash the SGB, but after inserting another cartridge, all it takes for the SNES to reset the SGB is to strobe a register bit and presto.
