Bigger font version of TV_TEXT

I'm doing some experimenting in my trusty iron horse, and I'm using one of the 2.5" LCD's from Tim (Lovely little display by the way).

All my code is based around tv_text as it does what I need and uses very little RAM. Unfortunately the text is just too small to read at a glance while driving. Has anyone knocked up a version of TV text with a bigger font?

    Can't you just reduce the number of columns and rows to make it bigger? I think the TV_text driver can scale to fit...

    No, it doesn't. It simply centers the display horizontally and vertically based on the width you end up with.

    Ok, so it's 3" and not 2.5". Either way the text is way too small to look at while driving [noparse]:)[/noparse]

    This is one of the first hacks I did; I need 4 lines by 20 characters, which I later expanded to 27 characters by narrowing them a bit, for a display to let truck drivers know their RFID cards had been scanned from the cab. You must change rows and cols, obviously, to reduce the number of characters, but also increase hx and vx to actually make the characters bigger. You have much finer control of horizontal size since hx starts out at 4 and vx starts out at 1.
