Unfortunately no. It should work if you'll add dummy 'con' argument
to the fb_ioctl, and dummy struct vc_data* to fb_check_var. Rest of
code should correctly branch according to the value of fbinfo's 
matroxfb_switch_con field, and fbops's fb_{get,set}_cmap, fb_putcs,
set_font and cursor fields (NULL => use cfb_imageblit for putc,
fb_cursor for cursor, and generic code for setfont and cmap).

I never tried to update new vesafb to this interface, as supporting
fbset on /dev/tty* was already vetoed long ago, and I have no problem
with maintaining it outside of tree.
                                            Best regards,
