OK, svgalib is supposed to do that by itself, but people like me who
don't generally trust software to not have bugs prefer using a
wrapper program. <URL:http://sites.inka.de/~bigred/sw/ioperm.txt>

I've given up on svgalib since I got a machine fast enough for X ;-)
but does svgalib support fbdev now? That would be a good transition
aid.
