Appears to work.  The ymfpci gameport seems to be somewhat unreliable:

 analog.c: 100 out of 17347 reads (0%) on pci0000:06:06.1/gameport0 failed
 analog.c: 122 out of 1111 reads (10%) on pci0000:06:07.0/gameport0 failed

There is still some dependence of the CPU speed on the loop counts
calculated by gameport_time(), but it's not very high; the following are
for 3200 and 800 MHz, 5 times each:

 gameport gameport7: EMU10K1 is pci0000:06:06.1/gameport0, io 0xe480, speed 651kHz
 gameport gameport8: EMU10K1 is pci0000:06:06.1/gameport0, io 0xe480, speed 651kHz
 gameport gameport9: EMU10K1 is pci0000:06:06.1/gameport0, io 0xe480, speed 651kHz
 gameport gameport10: EMU10K1 is pci0000:06:06.1/gameport0, io 0xe480, speed 651kHz
 gameport gameport11: EMU10K1 is pci0000:06:06.1/gameport0, io 0xe480, speed 651kHz
 gameport gameport12: EMU10K1 is pci0000:06:06.1/gameport0, io 0xe480, speed 612kHz
 gameport gameport13: EMU10K1 is pci0000:06:06.1/gameport0, io 0xe480, speed 612kHz
 gameport gameport14: EMU10K1 is pci0000:06:06.1/gameport0, io 0xe480, speed 612kHz
 gameport gameport15: EMU10K1 is pci0000:06:06.1/gameport0, io 0xe480, speed 611kHz
 gameport gameport16: EMU10K1 is pci0000:06:06.1/gameport0, io 0xe480, speed 612kHz
