To z deb balicku je aka verzia?

bodaj by nie. Pokial viem ziadne jadro 2.6.0 (presne tento nazov) v
balickoch nebolo. Takze ak mu davas initrd z ineho jadra tak tam ma
moduly v inom adresari. /lib/modules/{nazov_jadra}/modules.dep

Nasiel disk? Je ovladac (predpokladam) IDE disku priamo v jadre?

Najrozumnejsie je si prekompilovat jadro, tak aby vsetko, co natahuje
ako modul jadro distribucne po nabootovani, bolo priamo v jadre a nie
ako modul. Je to asi najbezpecnejsie pokial nevies naco, ktory modul je
a nevies kedy sa zavadza do pamate.

potom uz len nakonfigurovat lilo a spustit ho. Najlepsie s parametron -v
aby bolo vidiet ci kvoli niecomu nerepta.
