Sergey, thanks for the patch. A few things need fixing though.

0xffff isn't valid, it's BCD, so 0x9999 is the highest.

However, please don't include the whole range unless you have reason to
believe the whole range is affected. In this case just 0000 should do the
trick.

Can you send an updated patch and we'll get it included?

Thanks!
