Flashing GSM firmware

So fluid is still not flashing the image, but I noticed the following  
messages on the console
after my latest attempt:
The error message:
rxerr: port ch=0x00, rxs=0x0000000c

shows up in dmesg after I send the command:
echo "AT at POFF" >/dev/ttySAC0

Looking back through dmesg, this seems to be a pretty consistent  
error message:

modem wakeup interrupt                    <----result of " echo 1 >/ 
rxerr: port ch=0x88, rxs=0x00000004  <---result of "echo "AT at POFF" >/ 
rxerr: port ch=0x00, rxs=0x0000000c
rxerr: port ch=0x14, rxs=0x00000004
rxerr: port ch=0x61, rxs=0x00000004
rxerr: port ch=0x12, rxs=0x00000004

This happens consistently as a result of the following command sequence:
root at om-gta02:/usr/sbin# echo 0 >/sys/devices/platform/neo1973-pm-gsm. 
root at om-gta02:/usr/sbin# echo 1 >/sys/devices/platform/neo1973-pm-gsm. 
root at om-gta02:/usr/sbin# s3c24xx-gpio b7=0
root at om-gta02:/usr/sbin# echo "AT at POFF" >/dev/ttySAC0
root at om-gta02:/usr/sbin#

This is referenced in this bug report:

So it looks like my attempt to apply the fix for this bug may be  
getting stomped on by the bug itself :)
