I don't have kernel v2.6, but I have test my board with eldk-3.1.1 linux-2.4.25
when my board kernel booting, I found one problem.
eldk-3.1.1 linux-2.4.25 kernel include i2c, i2c-algo-8xx, pcf8563 driver.
If one pcf8563 chip on my board, there are't problem.
But if my board don't have pcf8563 chip, kernel stop as blow:

I modify i2c-algo-8xx.c cpm_iic_write(), then no problem,
my board defined by CONFIG_SVM8xx

#ifdef CONFIG_SVM8xx
    while(!(i2c->i2c_i2cer & 0x12))
      if (time_after(jiffies, tmo)) {
        tmo = 0;
        break;
      }
#else
                while(!(i2c->i2c_i2cer & 0x12 || time_after(jiffies, tmo))); /* Bus
#endif
