This has the following issues:

1)   CC [M]  fs/cifs/cifsfs.o
fs/cifs/cifsfs.c:409: warning: `cifs_umount_begin' defined but not used

2) The PS/2 keyboard death on ppp traffic is still not fixed. 
Reproducible even on slow GPRS if there's something else (e.g. glxgears) 
that eats some CPU time. When keyboard is dead, events/0 consomes 100% 
of CPU. Nothing in dmesg. If you outline some suspicious pieces of code, 
I will insert printks there in order to debug this.

3) There are some differences with dmesg of the vanilla 2.6.14. Could 
you please explain this (- = 2.6.14, + = 2.6.14-mm1)?

-pnp: PnP ACPI: found 11 devices
+pnp: PnP ACPI: found 12 devices

The command line parameters "noapic pci=noacpi" are present, and that's 
a VIA motherboard, if that's relevant.

4) I also decided to test new input hotplug. Below is the udevmonitor 
trace of uevents when I rmmod and modprobe again the psmouse driver. 
<NULL>s don't look right there. Is the rest OK?
