+To do list (not in any particular order).
+
+    o	Improve pmap_zero_page and pmap_copy_page. Speed and flushing.
+
+    o	Move the RO and WIRED attribute from the pte to the pv table.
+	This saves four instructions in the tlb miss handler.
+InWork: Have a test version. The system hangs after a while. Not solved yet.
+        Also, is it worth the effort to remove 4 instr. in TLB-miss handler?
+
+    o	Update MAKEDEV to create all devices correctly.
+
+    o	Add dos disklabel functionality so disks can be shared with NT.
+InWork: mformat needs to be hacked to handle disk labels. Need to figure
+        out what method to use (offseting?).
+
+    o   Boot. Standalone boot program instead of booting the kernel directly?
+
+    o   Create boot package for distribution.
+
+    o   sigsetjmp/siglongjmp missing....
+
+    o   Add more videomodes to pccons driver. 50kHz and 64kHz monitors?
+InWork: This seems to be hard. Need more info on the chip.
+
+    o   SONIC driver. Use the one from Theo as a start?
+
+    o   Find out why bitmap load to S3-928 flashes screen.
+Know why (enable linear mode). Need S3 info.
+
+    o   Would be nice to have Motif...
+
+    o   ELF shared libraries......
+
+    o   Recompile ghostscript to have X driver as well as Cannon BJ200.
+
+    o   GDB. The current one does not work correctly with current toolchain.
+
+    o   ISA driver. ISA dma, interrupt etc.
+
+    o   SONY cd-rom driver + sound driver. Uses ISA dma.
+
+    o   Can we have 32 double registers?
+
+
+Lots of other things.....
