+ * Original credits from the FreeBSD driver:

+ * Part of this code (especially in many magic numbers) was heavily inspired

+ *
+ * busdma()-ize and buffer size reduction were suggested by
+ * Cameron Grant <gandalf%vilnya.demon.co.uk@localhost>.
+ * Also he showed me the way to use busdma() suite.
+ *
+ * Internal speaker problems on NEC VersaPro's and Dell Inspiron 7500
+ * were looked at by
+ * Munehiro Matsuda <haro%tk.kubota.co.jp@localhost>,
+ * who brought patches based on the Linux driver with some simplification.
