Well, try POKE 36867,32*2 which will give you 32 lines of video matrix.
Obviously it will be filled with garbage unless you move the start of the
video matrix so the whole matrix is within VIC accessible RAM.

IIRC, more than 32 rows (256 pixels y-wise) won't display on the VIC, but
it is quite an improvement from the standard 23 rows. Regarding docs, you
shouldn't trust them unless you yourself have verified what the docs say.
