Hi,

currently on kernel-desktop586 HIGHMEM is disabled, mainly because there is
some slightly overhead with it enabled and this kernel was meant for old
machines with low memory. But the desktop586 is used on Mandriva One (to work
on most hardware as possible, even the older ones and not 686 compatible arch
cpus), and we get many reports of it not detecting all memory available,
because systems with more than 896MB are very common today.

I measured recently the boot time of a geode with 512MB with highmem4g
enabled/nohighmem and didn't notice a significant difference at least on boot
time (the difference was around 1s or less, still in some error margin). So
what about we rediscuss this again and now enable CONFIG_HIGHMEM4G also on
desktop586 kernel? I think that there are more benefits in enabling it.
