Size issues with kernels?

[John Klos <john%ziaspace.com@localhost>]

Hi,

I haven't had time to look into this in any great detail, but I was 
getting netbsd-7 going on a Seagate Dockstar using a SHEEVAPLUG config 
file without sdmmc, and the kernel wouldn't start. I removed a bunch of 
stuff (audio, Bluetooth, for instance) from the kernel config, recompiled, 
and it booted and ran just fine. I won't get to test soon, since this 
machine has to be set up for use, but I thought it'd be good to get some 
ideas for the next time I can play with a Dockstar. Suggestions?

Thanks,
John
