Oops again.  I see that irq 7 is *not* excluded in your
config.opts file.  The failure to grab irq 7 must therefore
be due either to another driver (such as parport) having
reserved irq7, or to the serial driver's failure to see the
card's UART ioports and irq.  Either way, as I said before,
I suggest you stay away from using irq 7 for PCMCIA cards.
Use irq 9.  If you like, try getting MIDI to work with irq 7
instead.  I think I am going to try doing that myself.
