kernel-2.6.14-1.1637, 1653: long delay after "Uncompressing..." phase

[Ville Herva]

Since kernel-2.6.14-1.1637, there has been a long delay during boot after
the "Uncompressing..." line. It takes about a minute or so, and judging
from the sound of the fan, it appears to take 100% CPU. Observed on a Compaq
AP250 PIII 866MHz. Earlier kernels did not have this glitch.

Ok:
 kernel-2.6.12-1.1398_FC4
 kernel-2.6.12-1.1447_FC4
 kernel-2.6.12-1.1456_FC4
 kernel-2.6.13-1.1526_FC4
 kernel-2.6.13-1.1532_FC4

Long delay (about minute or so):
 kernel-2.6.14-1.1637_FC4
 kernel-2.6.14-1.1653_FC4
