No, it doesn't. See


to find out that a boot loader should pass the address of the tag list in r2 
to the kernel. It's near the end. And then see


to see that 2.4-kernels currently don't use r2 and can't use in order to stay 
compatible. In fact, a 2.4. kernel trashes r2 right at the start, see


However, 2.5-kernels already employ the r2-rule.

I'm not sure, but I think that only Kernels for ARM (and for XScale) use this 
tagging at all, correct?

Ahh, here is the trick, use gd->bd->bi_boot_params
