All questions are related to i386 architecture where applicable.

1. Can current bootblocks boot kernel from level 1 ffs ?

   (I'm not going to convert my *extremely* stable FS's while seeing 
    fs-related panic reports on mailing lists, I still use 0.9 bootblocks)

2. I noticed that libgcc.a for NetBSD's gcc is much smaller than
   libgcc.a installed by stock gcc-2.6.0. (17KB vs 120KB). Can our
   libgcc.a be used instead of original libgcc.a when linking object files
   generated by gcc-2.6.0 ?

3. I need some hint on how code size/code speed tradeoff influences
   overall system performance in NetBSD. Would it be benefitial 
   if I could compile all code 5% smaller than usual and 8% slower 
   ( when cpu bound, locked in memory) on machine with 16MB memory
   and 1 swap partition on SCSI disk,running XFree,everything linked dynamic ?
   ( I'm prepared to build entire system)

4. Looking into current kernel sources I found that madvise and mincore 
   system calls are still unimplemented. Are there any plans to implement
   them ? 

Thanks in advance,
