2.6.4 not detecting all ram on TiBook 4

[Satadru Pramanik <satadru@umich.edu>]

I just upgraded the ram on my system from 512MB to 1024MB and the system
when running in linux does not detect all the ram on the system.  OS X
recognizes that two 512 MB PC133 SDRAM chips are installed.

dmesg shows this:


Total memory = 768MB; using 2048kB for hash table (at c0600000)
Linux version 2.6.4 (satadru@satmac) (gcc version 3.3.3 (Debian
20040306)) #1 Thu Mar 11 12:08:24 EST 2004


Do I need to compile my kernel with HighMem support?
