[ts-7000] TS-7260 DIO with 2.6.21-ts kernel

["Rekcut_Nod" <>]

If I run a little utility (see below) to read and write to the memory register 
corresponding to the DIO data on the DIO1 header of the TS-7260 board, I get 
different results depending upon whether I'm running the TS stock 2.4 kernel, 
or their (unsupported) 2.6.21-ts kernel.  Has anyone experienced this?  Has 
anyone found a way to get the DIO lines to work with the 2.6 kernel?

Any assistance is greatly appreciated!

utility source:

int main(int argc, char **argv)
{
volatile unsigned char *PBDR, *PBDDR;
unsigned char *start, ONE=0x1;
int fd = open("/dev/mem", O_RDWR|O_SYNC);
int i;

start = mmap(0, getpagesize(), PROT_READ|PROT_WRITE, MAP_SHARED, fd,
0x80840000);
PBDR = (unsigned char *)(start + 0x04); // port b
PBDDR = (unsigned char *)(start + 0x14); // port b direction register

*PBDDR = 0xff;// all output

for(i=0;i<8;i++)
{
 *PBDR = ONE<<i;
  printf("*PBDR=%02x\n",*PBDR);
  sleep(2);
}

close(fd);
return 0;
}

Results, with DIO_4 (pin 9) grounded:
2.4 kernel:
PBDR=01
PBDR=02
PBDR=04
PBDR=08
PBDR=00
PBDR
PBDR=40
PBDR=80
2.6 kernel:
PBDR=0f
PBDR=0f
PBDR=0f
PBDR=0f
PBDR=0f
PBDR=2f
PBDR=4f
PBDR=8f
