I usually read it directly from the BIOS variables.  There are functions to
return the video mode and number of columns and base address, but nothing that
I can see will tell me how many rows.  So, if the mode is "3", I just peek into
the standard BIOS variable locations to get the number of rows.

This, by the way, allows support for 30,40,43,50,60 lines in text mode, 
in addition to the "standard" 25 lines.
