I found (and fixed) that now.

The datasheet erroneously specifies 6 address bits per page for the
page load and page write instructions, but these devices do have only
32 words per page (i. e. 5 address bits).  Moving the "a5" name from
the loadpage_{lo,hi} definitions to the writepage one fixes writing
through bit-bang programming adapters (like the STK500).

Never trust an operating system you don't have sources for. ;-)
