I have a two-port PCI serial card. I'm running FreeBSD 6.2-RELEASE on i386 and 
trying to get the card working using kernel modules puc and uart (after much 
Googling this seems like a viable option).

With the GENERIC kernel, the boot process recognises my card as <simple comms, 
UART> but can't find the driver for it. When I kldload puc, the card is 
recognised as NetMos NM9835:

puc0: <NetMos NM9835 Dual UART and 1284 Printer port> port 
0x6c00-0x6c07,0x7000-0x7007,0x7400-0x7407,0x7800-0x7807,0x7c00-0x7c07,0x8000-0x800f 
irq 12 at device 11.0 on pci0

but when I kldload uart, whether before or after puc, I don't see any new 
devices appear, nor do I get any dev.uart.* sysctls.

Am I missing something obvious, or do I need to compile yet another custom 
kernel to get this card working?
