linux/isapnp.h has the following code:

#if defined(CONFIG_ISAPNP) || (defined(CONFIG_ISAPNP_MODULE) && defined(MODULE))

#define __ISAPNP__

I believe the pnpbios driver should do things something similar. Users of
the interface should then only check for #ifdef __PNPBIOS__.

The reasoning behind this is the following: When you have a driver
built-in, but pnpbios modular, the driver cannot use pnpbios
functionality. The above definition reflects exactly this.

(BTW: The drivers using ISAPnP functionality seem to generally get this
wrong, I'll look into cleaning this up. In drivers/scsi/aha152x.c it's
done right)
