ttyS3 on breakout-gs

Sorry for the oft asked question, but I have not been able to find the 
right combination of responses to work for me so far.  I have a gumstix 
200 without bluetooth.  I have connected it thru a waysmall board and a 
full cable to a serial gps with no problems.  I am now trying to make 
the same connection to the new breakout-gs on HWUART.  I realize that my 
problem relates to CTS, RTS and DTR but haven't found the right solution 
yet.  I edited the pxa.c file as described in previous comments to 
similar problems (removed 4 lines in the function serial_pxa_set_mctrl) 
and rebuilt the root file system, which I loaded onto the gumstix.  I 
edited the scripts in init.d to not start bluetooth and created one to 
run the following:
modprobe proc_gpio
# AF1 are alternative function 1 from the pxa25 developers manual 
(section 4.1.2)
# gpio48 is hwuart txd
echo AF1 out > /proc/gpio/GPIO48
# gpio49 is hwuart rxd
echo AF1 in > /proc/gpio/GPIO49
# gpio50 is hwuart cts -- lets reset this to gpio in for a test
#echo AF1 in > /proc/gpio/GPIO50
echo GPIO in > /proc/gpio/GPIO50
# gpio51 is hwuart rts -- lets reset this to gpio in for a test
#echo AF1 out > /proc/gpio/GPIO51
echo GPIO out > /proc/gpio/GPIO51

# 42-45 are alternative versions of the hwuart pins (used by bluetooth)
for i in 42 43 44 45;do echo GPIO in > /proc/gpio/GPIO$i;done

# set the terminal with no controls
stty -F /dev/ttyS3 clocal -ixon -ixoff -crtscts speed 4800

When I run cat /proc/tty/driver/PXA\ serial  -- while a program is 
accessing the /dev/ttyS3, I get this
serinfo:1.0 driver revision:
0: uart:FFUART mmio:0x40100000 irq:15 tx:312 rx:0 RTS|CTS|DTR|DSR|CD|RI
1: uart:BTUART mmio:0x40200000 irq:14 tx:0 rx:0
2: uart:STUART mmio:0x40700000 irq:13 tx:0 rx:0
3: uart:HWUART mmio:0x41600000 irq:0 tx:49522 rx:41283 fe:10427 brk:136 
RTS|CTS|DTR

After access is completed I get this
cat /proc/tty/driver/PXA\ serial
serinfo:1.0 driver revision:
0: uart:FFUART mmio:0x40100000 irq:15 tx:312 rx:0 RTS|CTS|DTR|DSR|CD|RI

2: uart:STUART mmio:0x40700000 irq:13 tx:0 rx:0
3: uart:HWUART mmio:0x41600000 irq:0 tx:55710 rx:46392 fe:11596 brk:158 CTS

No data is accessable at /dev/ttyS3 though.
My "build" was from sometime in late June, and I noticed tonight that 
Craig had added a HWUART patch in early July, so I picked up the new 
stuff from svn tonight (version 516),but the make fails (this is a new 
problem, I make my root_fs because I need crond in busybox -- my system 
is FC4) late in the processing with this message:

Currently I am stumped any help will be greatly appreciated.
Sorry for the long post
