You don't have to use variables (although it's better for a long
term).  The problem is that you have two modules.  Combining them to a
single module wouldn't be too hard.

For example, compile layla and gina separately, but without
module_init and module_exit.  Create a skeleton PCI entry which calls
layla's and gina's driver callback functions.
The reference to module options should be fixed, too.

We may have, but we can't load them at the same time.
It's a tacit understanding that the drivers with the same id
conflict.
