>Description:
DNS lookups in linux32 processes do not work. The lines I think are relevant in 
ktrace output are:

   427   2229 firefox-bin NAMI  "/emul/linux32/etc/resolv.conf"
   427   2229 firefox-bin NAMI  "/etc/resolv.conf"
   427   2229 firefox-bin RET   stat64 0
   427   2229 firefox-bin CALL  gettimeofday(0xf68fd954,0)
   427   2229 firefox-bin RET   gettimeofday 0
   427   2229 firefox-bin CALL  socketcall(1,0xf68fd860)
   427   2229 firefox-bin MISC  socket: 12, 020000000208000000000000
   427   2229 firefox-bin RET   socketcall -1 errno -91 Protocol wrong type for 
socket

I have not tested 64 bit linux code.
>How-To-Repeat:
Run 32 bit Linux Firefox. Access to addresses in hosts file or by IP work but 
DNS does not work.
