No. Any i386 boot loader should pass its own type to Linux (See
"Documentation/i386/boot.txt", for more information), but Linux
doesn't export the type to the user-land.

I don't think there is any robust way for that. Suppose that you can
determine which booted your Linux kernel. Even with this information,
you cannot determine which is _normally_ used. The user may boot it
another way.
