Possibly worth noting is that Juniper seems to only use Silicon Systems
for 1GB CF. At least every 1GB card we have received from Juniper is
Silicon Systems. 

We have a bunch more on order, but we only have a few in hand at this
time, so it the sample may not be statistically valid, especially when
the ones we have were purchased at about the same time.
