Here's a binary patch for the leap year bug that will work for Sun 4s.

# adb -w -k /vmunix /dev/mem
resettodr+0x110?X
	(It should contain 0xba276001, a sub %i5, 0x1, %i5 instruction.
	(Change it to a nop in both /vmunix and kernel memory)
.?W 0x1000000
./W 0x1000000
	(To make yourself feel better, do the following)
.?i
./i
	(If they're nop's, things should now be better)
$q

We are running the SYS4 GAMMA release, but things should be the same
for SYS4 3.2.  If not, here's the original GAMMA binary and you can go from
there.
