hi, if you like rh9, try fedora core 3 - see http://fedora.redhat.com/
for more details.
i guess you'lll need the following ISO images for amd64:
For x86_64 (64-bit AMD64, EM64T):
FC3-x86_64-disc1.iso (md5sum: b61b0eb7e0171837aeeff4f0054a4d79)
FC3-x86_64-disc2.iso (md5sum: 99dc12c7e8a93844a48a5675a9c07ec9)
FC3-x86_64-disc3.iso (md5sum: 399b7ffd721ebb4244a02c34cdbb1b82)
FC3-x86_64-disc4.iso (md5sum: f58b1de3b880df55dbbd37d143419226)
i would be very interested if this installs ok as i'm also about to purchase an acer aspire 1524.
does firewire, NIC, USB etc work OK? good luck
