+DRIVER PARAMETERS
+================================================================================
+
+  Some functions for the cm8738 can be configured in Kernel Configuration
+  or modules parameters. Set these parameters to 1 to enable.
 
-1. Real player cannot be run (the same as es1371).
+  spdif_loop:   Enable S/PDIF loop, this route S/PDIF-in to S/PDIF-out
+                directly.
+  four_ch:      Enable 4 channels mode, rear-out or line-in will output
+                the same as line-out.
+  rear_out:     Enable this if you have independent rear-out jacket on
+                your sound card, otherwise line-in will be used as
+                rear-out.
+  modem:	You will need to set this parameter if you want to use
+		the HSP modem. You need install the pctel.o, the modem
+		driver itself.
+
+  (You will need to get the pctel driver (binary only) and the support for
+  this option from the CMI site. It is not included in the Linux kernel 
+  proper as it is non-free).
