what version of landesk are you running.
Sorry, it is 8.7 sp5
try these drivers - http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=12454&prodSeriesId=4024563&swItem=vc-74977-1&prodNameId=4024580&swEnvOID=1093&swLang=13&taskId=135&mode=4&idx=0
then put the files that are in sp45407\driver\x86 into a folder called amd.msd (in a flat sctructure)
put that amd.msd with the other driver folders that wpedownload.exe downloaded and then run the wpedrivers.exe.
Hopefully that will work..
