 Many, many things. Most notably:
 
-* Sensors program needs to print a + before lm75 temperatures
-* Timer chips - block read problems?
-* Library: reload does not work (Bison/Flex problem?)
-* Create wait-queues for bus locking instead of pure semaphores, to make
-  it more interactive
-* Check for block read/writes in smbus-on-i2c emulation code
-* Better bounds checking for writes to /proc; fan_min values now checked
-  but other features may need too.
+KERNEL MODULES
+==============
+
+* Module documentation!!!
+* maxilife.c: Introduce new insmod variables
+* maxilife.c: Round REG_TO_VID correctly
+* icspll.c: Rewrite. The current implementation simply can't work at all.
+  It needs i2c-level access (too bad for SMBus-only adapters).
+* Create wait-queues for bus locking instead of pure semaphores in the i2c
+  base modules, to make it more interactive (right now one process can 
+  monopolize the entire adapter)
+* Find some soulation for block reads in smbus-on-i2c emulation code
+  We need a hack in the i2c level code for this :-(
 * At least the bit-lp and bit-velle modules do no detection on loading;
   ask Simon whether this is possible to add.
-* kmalloc with GFP_KERNEL can cause a context switch! Check whether this is
-  safe everywhere it is used.
 * Support 10-bit addresses. At this moment, they are supported nowhere, except
   in Simon Vogl's i2c modules.

 * Test SIS5595(/91/98) sensor support. Write generic i2c support. 
   Thomas Dickel <Thomas.Dickel@mni.fh-giessen.de> owns one SIS5595.
 * Make GL518SM rev 00 voltage iteration run as a kernel thread.

+LIBRARY
+=======
+
+* reload does not work (Bison/Flex problem?).
+* Some library routines are pretty inefficient right now.
+* Library should be split in more separate files, for better linking
+  behaviour.
+* Many chips are not yet supported by the library.

+PROGRAMS
+========
+
+* Sensors program needs to print a + before lm75 temperatures
+* Sensors program needs to be extended for many new chips
