The machine has two memory slots, supporting a maximum of 512 MB RAM. It came with a single 128 MB memory module and I purchased an additional 256 MB for a total of 384 MB.
The VAIO manual says to use PC100 (CL2) SDRAM SODIMMs.
Toshiba model MK1517GAP 15 GB ATA/IDE
The disk came with two partitions; one held Windows XP Home Edition and the other was empty. This was convenient since I was able to delete the empty partition and install Linux on it without affecting Windows.

I enabled 32-bit I/O transfers by editing /etc/sysconfig/harddiskhda (copied from /etc/sysconfig/harddisks):

Matshita model UJDA710 CD-RW/DVD combo drive; 8x CD-R, 4x CD-RW, 24x CDROM, 8x DVD
Note that this drive is region locked (RPC-2) and that there's currently no known way to disable it.
The drive is manufactured by Matsushita Electric Industrial Co., Ltd., also known as Matsushita Kotobuki Electronics Industries, Ltd., or better known in the U.S. as Panasonic.
I haven't tried it with Fedora yet, but with Red Hat 7.2 I successfully burned CD-Rs using cdrecord and watched DVDs with Ogle.
Integrated 10BASE-T/100BASE-TX ethernet
I had some initial trouble transferring large files. The driver would complain about timeouts and the connections would hang.
Thanks to Jan Slupski, I learned this was due to the sleep mode being enabled on the card. I fetched the eepro100-diag.c utility and followed Jan's instructions. First I verified that sleep mode was enabled by examining the output of:
$ ./eepro100-diag -e -e f ... Sleep mode is enabled. This is not recommended. Under high load the card may not respond to PCI requests, and thus cause a master abort.
Then I disabled sleep mode with the command:
$ ./eepro100-diag -G -w -w -w -f
The timeouts vanished and I haven't experienced any problems since.
Conexant Integrated V.90/K56flex Winmodem
I haven't tested it with Fedora, but I had it working with Red Hat 7.2 using the Conexant HSF driver.
USB works fine once ACPI is enabled. My USB mouse didn't require any additional configuration.
I'm using a NetGear MA401 802.11b wireless PC Card.
I had to enable ACPI by adding the acpi=on boot parameter to /etc/grub.conf:
$ diff -u /tmp/grub.conf.orig /etc/grub.conf --- /tmp/grub.conf.orig 2003-11-28 03:24:13.000000000 -0800 +++ /etc/grub.conf 2003-11-15 16:16:18.000000000 -0800 @@ -12,5 +12,5 @@ splashimage=(hd0,0)/grub/splash.xpm.gz title Fedora Core (2.4.22-1.2115.nptl) root (hd0,0) - kernel /vmlinuz-2.4.22-1.2115.nptl ro root=LABEL=/ hdc=ide-scsi rhgb + kernel /vmlinuz-2.4.22-1.2115.nptl ro root=LABEL=/ hdc=ide-scsi rhgb acpi=on initrd /initrd-2.4.22-1.2115.nptl.img
