Ze zmen udelanych po 7.0-RELEASE:

	Tohle by mohl byt prave tento pripad (neni to ale jiste - z toho 
neverbose LOGu se zda, ze pozadovana pamet 4k neprevysovala).

	Pokud by to byl tento problem pak moznym resenim je pouziti 7-STABLE

	No, teoreticky je mozne podivat se na to, jestli je promenna tohoto 
jmena s udanou hodnotou v environmentu kernelu opravdu pritomna (a zda 
je tam vcas - nejsem si totiz jist, jestli staci, aby byla nastavena az 
pred prvnim pouzitim - zda ji neni potreba nastavit uz pred nahravanim 
modulu - a to ty nemas).

	Ale ve skutecnosti bych se asi timhle problemem nezabyval, dokud nebude 
vyreseny problem s neuspesnou alokaci pameti.
