two laptop X issues on 4.0.1

[der Mouse <mouse%Rodents-Montreal.ORG@localhost>]

I don't know if this is the right place to ask these, but tech-x11
seems somewhat righter than port-i386, the other contender....

(1) Is there any interest in bugs in 4.0.1/i386's xsrc-built X?  It
misinterprets a cursor mask of None in a fairly specific way.  I'm
wondering if there is anywhere it would be of any use to report it.

(2) On my laptop, X claims to be 1024x768, and appears to be running at
the screen's native resolution - but it appears the screen is actually
1024x767; the bottom row of pixels of the X screen do not actually get
displayed.  I tried adding Modes "1024x767" to my XFree86Config, to no
avail; XFree86.0.log reports "Replaced entire mode list with built-in
modes", which looks probably related.  But I'd mostly like to know if
there's any way to fix this, or if I'm just stuck with broken X.  (I'm
not afraid of patching the SIS ddx module if necessary - the hardware
is "(--) PCI:*(1:0:0) Silicon Integrated Systems [SiS] 630/730 PCI/AGP
VGA Display Adapter rev 49, Mem @ 0x88000000/27, 0x80000000/17, I/O @
0xa000/7".  But, while I've done ddx-layer hacking, I've never done so
inside the XF86-specific bits, so it would likely take me a fair while
to fix this on my own.)
