Judging by
<http://www.chiark.greenend.org.uk/~sgtatham/putty/wishlist/foundry-ignore-bug.html>
you need to enable the "Chokes on SSH1 ignore messages"
bug-compatibility mode (see
<http://the.earth.li/~sgtatham/putty/0.55/htmldoc/Chapter4.html#S4.20.1>).

(Normally PuTTY attempts to guess whether to enable bug compatibility
modes by the version string, but in the last report we had, the Foundry
device's version string was too similar to that of other, non-buggy
servers.)

I can't explain this behaviour, though (I don't think PuTTY will use
SSH_MSG_IGNORE packets during SSH-1 public key authentication, although
I haven't checked).
