Thats the base address of the struct. Please check the address of the
STS register instead (&i2c->sts). It it still different from the IIC_STS

If the addresses really are different, then its a bug. Most likely only
for the 440SX (correct?). I suggest you dig into this a bit deeper to
find the root cause for this address difference.
Hope this helps,
