you name it ;)

'til now i use Sun (and one sgi ;) only for this purpose. i have to 
replace a broken peecee (are there any non-broken peecees put there? 
SCNR), so this one will go out to an NewWorld machine i guess. 
nevertheless you have to find a _really 'professional'_ provider in 
germany, which is not that easy. professional -> can provide serial 
access || has heard of 'PortMaster' etc. :/

yip, then i'll give it a shot tomorrow morning.

but this is not required, is it? the thing is that i want to get access 
to a kernel which drops into DDB while booting.
