SUMMARY: Has anyone seen LP options changes under Solaris 10 (05/08)?

Found it, and the only fix is to modify the 'interfaces' scripts to 
accept both pre and post PAPI boolean options.

With Solaris 10 05/08, Sun implemented the PAPI interface, to support 
multiple printing back ends.  (BSD/IPP/CUPS/...)

The lp command calls the papiAttributeListFromString() function to 
process each option.

The papiAttributeListFromString calls a _parse_attribute_list() 
function, who job it is to process the numerous option argument 
formats.  Near the end of the function, it process boolean (key only) 
options. The first thing the boolean key code does is convert the 
boolean key into a key=value pair, with the key being set to a value of 
"true".  It then test the first two characters of the key to see if it 
begins with "no". If it does, it removes the "no" prefix, and sets the 
new key to "false".  (ie: "banner" becomes "banner=true". "nobanner" 
becomes "banner=false".)
    (lines 853-861)

Thus the only fix is to go through each interfaces script, and modify 
the code that process the options, to accept both 'key' and 'key=value'
