Thanks to: Andrew J Caines, Ed Sanborn, Casper Dik to name a few.

The responses were mixed between, "You need to reboot to lad the driver"
and "Take a look at Andrew's script in the archives (sorry I missed

Anyway, what I've found now on several machines is that I can install the
patch like the following and all seems fine:

Patch number 112438-01 has been successfully installed.
See /var/sadm/patch/112438-01/log for details
Executing postpatch script...
Reboot client to install driver.

Patch packages installed:

ymir:/tmp% rem_drv random
ymir:/tmp% add_drv random
ymir:/tmp% ls -l /dev/random
lrwxrwxrwx   1 root     other         33 Jul 23 14:32 /dev/random ->

ymir:/home/ops% ls -l /dev/urandom
lrwxrwxrwx   1 root     other         34 Jul 23 14:32 /dev/urandom ->

modinfo |grep random
122 10221aa2   1dea 217   1  random (random number device v1.1)

After this i did a:

ymir:/tmp% dd if=/dev/random of=foo bs=512 count=1
1+0 records in
1+0 records out

and this outputed random garbage to foo. After this I was able to
recompile, and install OpenSSH and have it use the random device.
