I had a HGC-1280 with a HMM-1900E running happyly with XFree86 under
Linux 'till the card died :-((.
Hope we are talking about the same card: the card does 1280x960 at
1bpp with 66Hz, and I tweaked it to 1280x1024 with virtual width 14xx.
In low res graphics mode, it is Hercules compatible.
Never heard of 1600x1280 interlaced for this card.

The card is supported, however, it was afaik never tested under FreeBSD.

The monitor is NOT VGA-compatible! It is fixed frequency (66kHz, 66Hz),
and ECL coupled! While the monitor input would be able to display
grey scales, you would need some kind of adapter circuit. Not a trivial
thing at 110MHz.
