Setiathome _is_ running at nice +19...  The H6 version cured the 2.4.17 boot
problem here.  Here are some numbers (H6) for you to consider:

make bzImage with setiathome running nice +19

make bzImage  391.11s user 30.85s system 62% cpu 11:17.37 total

make bzImage alone

make bzImage  397.33s user 32.14s system 92% cpu 7:43.58 total

Notice the large difference in run times...

System is: UP K6-III 400, 512M
