I built off of a new source tree with the following changes:
* SMP = 1 commented out of Makefile
* Boomerang driver 3c59x.c-0.46C replacing the existing useless
0.25 one. (0.46C doesn't build cleanly as a non-module until the
MODULE_AUTHOR, MODULE_DESCRIPTION, MODULE_PARM calls are guarded
by an ifdef MODULE - patch appended).
* drivers/sound/softoss.c: `#include <sys/ultrasound.h>' replaced with
`#include <linux/ultrasound.h>'.
The F0 0F trapping works differently than it did in 2.1.63. In .63
all the exploit programs I tried dropped core with an `illegal
hardware instruction' message (I had also applied the patch in
<Pine.LNX.3.95.971112175917.444E-100000@penguin.transmeta.com>).
In .64 it oopses:

[The syslog and output from dmesg stops here]
* I got the following error messages when doing the initial `make
