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