Well, if you can prove that any existing AVR910 could handle block
mode even for target AVRs that cannot handle page mode, we can remove
this.  So far, the term is "paged_write", rather than "block_write",
which indicates that it will program an entire page.  Obviously, this
does not make sense if the device does not implement page writes at
all.

Note that butterfly (aka. AVR109) should not have any issue with that
because as far as I know, and device that is able to self-program does
also offer page write capabilities.
