-From: Petr Vandrovec <vandrove@vc.cvut.cz>
-
-Patch below adds support for using different prescaler than 16 for 16c950
-chips.  This is needed for using Fujitsu-Siemens Connect2Air compact-flash
-card, which comes (apparently) with 806kHz clocks, and so you have to
-program prescaler for division by 7, and DLAB to 1, to get 115200Bd.  
-
-To get card properly running you also have to add lines below to
-/etc/pcmcia/serial.opts so kernel knows that base speed is not 115200 but
-50400 (50400 * 16 = 806400; 806400 / 7 = 115200).  As I've found no code
-specifying baud_rate in serial_cs, I assume that specifying it in
-serial.opts is right way to do this type of things.
-
-Patch also fixes problem that for UPF_MAGIC_MULTIPLIER maximum possible
-baud rate passed to uart code was uartclk / 16 while correct value for
-these devices (and for 16c950) is uartclk / 4.
-
-Patch also fixes problem that for UPF_MAGIC_MULTIPLIER devices with
-baud_rate 19200 or 9600 spd_cust did not work correctly.  Not that such
-devices exist, but we should not ignore spd_cust, user probably knows why
-he asked for spd_cust.
-
-serial.opts:
-
-case "$MANFID-$FUNCID-$PRODID_1-$PRODID_2-$PRODID_3-$PRODID_4" in
-'0279,950b-2-GPRS Modem---')
-    SERIAL_OPTS="baud_base 50400"
-    ;;
-esac
