My implementation of 2D acceleration used the original buggy code in the staging tree (which had been removed due to a critical bug soon after its submission), also, OpenBSD's smfb.c driver written by Miodrag Vallat was another important source of reference, a hunk of hardware register definitions are taken verbatim.
This commit appends my name to the list of authors, and included Miodrag Vallat's name and the ISC license of the original smfb.c driver.
