This is correct. See https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility 
for more information.
It is not clear to me from this mail and the patch though whether there is a 
problem and what it is. 

The patch does not appear to create any additional linkage between SeaBIOS and 
Hvmloader (unless it was there before, in which case we already have an issue). 
Is this correct?

If so, then this becomes a question of what "this code is ported from SeaBIOS" 
exactly means and whether that implies a licensing issue. In other words, were 
any portions of files from SeaBIOS copied, etc. If so, what exact license were 
these under, etc. Maybe you can clarify.

Lars
