Sound Blaster 16 on FreeBSD 5.2

[Alejandro 'Lanjoe9' Valenzuela]

Hello everyone
I'm trying to use a Sound Blaster 16 ISA card in FreeBSD 5.2.1.
When I try recompiling the kernel as the Handbook specifies in order to 
make it work, config returns

"Config:277: Devices with 0 units are not likely to be correct"

If I remove the 0 (from sbc0 to sbc),  config returns a syntax error 
message.

I've tried a few hundred permutations in /boot/device.hints with the 
irqs, drqs and flags and it hasn't worked
it always returns these messages:

alloc_resources
probe_and_attach returned 6

What am I doing wrong? I never had any problems to make the sound card 
work in FreeBSD 4.9...

BTW how do I tell the computer not to recover vi sessions?

Thanks a lot in advace.
Alejandro
