14 * Daniel J. Rodriksson: Modified sbintr to handle 8 and 16 bit interrupts
15 * for full duplex support ( only sb16 by now )
16 * Rolf Fokkens: Added (BETA?) support for ES1887 chips.
17 * (fokkensr@vertis.nl) Which means: You can adjust the recording levels.
18 *
19 * 2000/01/18 - separated sb_card and sb_common -
20 * Jeff Garzik <jgarzik@pobox.com>
21 *
22 * 2000/09/18 - got rid of attach_uart401
23 * Arnaldo Carvalho de Melo <acme@conectiva.com.br>
24 *
25 * 2001/01/26 - replaced CLI/STI with spinlocks
26 * Chris Rankin <rankinc@zipworld.com.au>
