gta02, 2007.2: state of upgrades

[arne anka]

i am i bit at loss with the current state of avaliable updates (server  
glitches, 404, checksums instead of dates and kernel images/modules).
- what u-boot is recommended
- what kernel
- how did the missing modules depencies working out and the 0b kernel  
images

is it safe to upgrade w/o spending half a day afterwards to get everything  
up and running again?
