This is from kpathsea.info:
4.4 Suppressing warnings

Kpathsea provides a way to suppress selected
usually-harmless warnings;
this is useful at large sites where most users are not
and thus the warnings are merely a source of confusion,
not a help.  To
do this, you set the environment variable or
configuration file value
`TEX_HUSH' to a colon-separated list of values.  Here
are the

     Suppress everything possible.

     Suppress mismatched font checksum warnings.

     Suppress warnings when a character is missing from
a font that a
     DVI or VF file tries to typeset.

     Don't suppress any warnings.

     Suppress warnings about attempts to access a file
whose permissions
     render it unreadable.

     Suppresses warnings about an unimplemented or
     `\special' command.

`tex-hush.c' defines the function that checks the
variable value.  Each
driver implements its own checks where appropriate.
This is currently not handled by pdftex.

Not Knuth's warnings. 
But pdfTeX in PDF mode is also a driver...

The only one that IMHO matters is "special". OTOH nobody has
complained about this yet...

This only affects the backend driver, right? But not Knuth's
warnings in the web source.
